His initial laboratory results showed elevated liver enzymes. (B) Contrast-enhanced (intravenous and oral) abdominal CT axial image in the portal phase done 18 months prior while ambulatory, showing a small (17 mm) hypodense homogenous splenic lesion. Download Full PDF Package. The Spleen and Sickle Cell Anemia: A Contrast Enhanced Computerized Tomography Based Study. A patient with cystic lesions containing small daughter peripheral cysts (wheellike structures), a patient with concomitant disease in the liver, and a patient from an area where the disease is endemic should make hydatid disease suspect ( Fig. Multiple hypodense, non-enhancing splenic lesions are a nonspecific finding seen in lymphoma, sarcoid, fungal microabscesses, and opportunistic infections. The splenic lesion was further evaluated with CT, MRI. Cystic splenic hydatid disease can be difficult to differentiate from other splenic cystic lesions. Twenty-three months later, serum CEA elevated to 19.9, and an abdominal CT revealed that the splenic lesion increased in ⦠Splenic lesions tend to be small or infiltrating and vary in size and configuration, making detection difficult, particularly without use of an organ-specific contrast agent. Impression: indeterminate hypodense MADD in ⦠Incidental Splenic Lesions. Just so, are spleen lesions common? Although most hypodense lesions of the spleen can be considered benign, some findings and clinical conditions warrant closer attention to the lesion. Nodules tend to be innumerable and variable in size. Please find my observations below. So I became interested in seeing the CT scan report from last Oct., which says I have a "hypodense lesion posterior aspect of spleen not seen on previous study measuring 1.4 X 1.3 cm which was not seen on the previous study. The patientâs systemic symptoms with splenomegaly with multiple hypodense splenic lesions raised high suspicion for a primary hematologic malignancy or a primary splenic tumor. Although the majority of the lesions are benign, some findings require further attention and investigation. Twenty patients had multiple splenic lesions. The most common malignancies to metastasize to the spleen are lung cancer, breast cancer and melanoma. Microabscesses in the liver (black arrows) and spleen (white arrows) visible as small round, hypodense lesions with minimal peripheral enhancement. 2A, 2B).The lesion was isodense compared to the surrounding splenic parenchyma on the 5 minutes delayed images (Fig. Axial C+ portal venous phase. An elderly man with fever and hypodense lesions in the spleen and liver. A hypodense well defined lesion with some internal enhancement in the arterial and venous phases was demonstrated on the contrast enhanced CT scan (Fig. 35). MR imaging is an excellent imaging tool for diagnosis, evaluation, and characterization of various focal splenic lesions and pathologic conditions. [2] [5] [9] Angiosarcoma is exceedingly rare; however, it is the most common primary malignant vascular tumor of the spleen. The spleen is not enlarged and there are no enlarged lymph nodes in the splenic hilum. No evidence of peripheral enhancement of the hepatic lesions or ascites was documented. The spleen is an organ which is a part of the lymphoreticular system. (c) In the portal phase, there is ⦠Brief Answer: Your daughter has a reduced immune state with following spleen conditions Detailed Answer: Hi XXXX, Thanks for writing in to us. Diagnosis: cystic spleen (cystic lienis). Computed tomography of the spleen: how to interpret the hypodense lesion. CT can be diagnostic if the collection contains gas, but this is a rare finding. Another possible cause of splenomegaly is juvenile rheumatoid arthritis . This condition can cause inflammation of the lymph system. Because the spleen is part of the lymph system, this inflammation can cause the spleen to become enlarged. On CT, a splenic abscess typically is manifested as a unilocular or multilocular, hypodense collection or complex cystic lesion with an enhancing rim after intravenous administration of contrast material ( Fig. 2 ). Splenomegaly was seen in all 3 cases and multiple small hypodense nodular lesions in 2 cases on post-contrast CT. Lymphoma can also cause "hypodense" lesions in the spleen. Hypodense lesions in the spleen suggested that the patient was not suffering from any abdominal tumor. Differential diagnosis of multiple hypodense lesions in the spleen with granulomas on histology will include infective aetiology like M. tuberculosis, inflammatory conditions like sarcoidosis and lymphoma.3. Figure 1. 1). Imaging findings are non-specific, and knowing the presence of Gaucher disease is helpful in the differential diagnosis [ 90 ]. Teaching Points. An 82-year-old man with a history of hypertension and prostatectomy for benign hypertrophy was admitted with left flank pain of sudden onset. Haemangiomas, congenital in origin, represent the most common benign lesions of the spleen. With coalescence, a diffusely infiltrative appearance with concurrent hepatosplenomegaly may result. Although most hypodense lesions of the spleen can be considered benign, some findings and clinical conditions warrant closer attention to the lesion. Hypodense lesions in the spleen suggested that the patient was not suffering from any abdominal tumor. hypodense lesions which did not respond to broad-spectrum antibiotics. (b) During the arterial phase after intravenous gadolinium contrast enhancement, the spleen shows a serpentine-cordlike pattern. Eighteen months later, a 2-cm solitary hypodense lesion was detected in the spleen on CT, but serum tumor markers remained within the normal limits. Note an enlarged spleen with hypodense lesions. Incidental splenic lesion (an approach) Dr Jeremy Jones and Dr Matt A. Morgan et al. The sonographic findings of 53 cases of verified focal splenic lesions, excluding post-traumatic haematomas and phleboliths, were retrospectively analysed. According to Marmery, the splenic lesion is classified from Grade 1 to Grade 3, and the grade increases according to the depth of the laceration [14, 27]. 1: CT scan showing hypodense lesions in spleen and liver. The underlying cause of the splenic lesion will determine the treatment plan. On ultrasound, splenic IPT appears as a well-defined hypoechoic lesion within the spleen as seen in our case [10]. They will be detected in as much as 30% of people over 40 who undergo imaging tests. Modality: ultrasound of spleen. The spleen is the largest lymphoid organ with a parenchymal structure in the entire body. Osteolytic lesions in a few thoracic vertebrae were consistent with bone metastases or granulomatous disease, but bone marrow biopsy was inconclusive. Most of these diseases give rise to non-specific focal hypoechoic lesions on sonography. Although most hypodense lesions of the spleen can be considered benign, some findings and clinical con-ditions warrant closer attention to the lesion. Please seek evaluation by a hematologist soon. From the Archives of the AFIP: Primary Vascular Neoplasms of the Spleen: Radiologic-Pathologic Correlation. Hypodense splenic lesions are frequently encountered on abdominal CT images. The authors present a series of selected cases to show the value of computed tomography (CT) and magnetic resonance (MR) imaging in depiction of splenic disease. 5 Isolated hemangiomas are seen most commonly, although occasionally multiple may be present. All the patients underwent abdominal CT or MRI, all had splenomegaly, eight had hepatomegaly, and seven had intraabdominal lymphadenopathy. (a) Fat-suppressed T1-W image shows the spleen (asterisk) as being isointense to slightly hypointense to the muscle. Upon ultrasound analysis, chronic disseminated candidiasis does not usually demarcate before ANC recovery. Microscopic involvement of the spleen is present in ~75% of cases, but imaging procedures (CT, ultrasound, MRI) unravel innumerable small hypodense nodules only in about 5â10% of cases . Of the 53 cases, 30 cases (57%) were benign and 23 cases (43%) were malignant. Whereas most calcified splenic lesions are presumed to be sequel-ae of prior granulomatous infection, there is a broader differential diagnosis for these lesions. Splenic Gaucheromas are generally observed as hypodense lesions on CT and multiple nodular lesions with variable signal intensity on MRI (Fig. Treatment. [2] The majority of solitary splenic lesions identified with CECT are of primary splenic origin, eg, hemangioma, Hypodense splenic lesions are frequently encountered on abdominal CT images. Noncancerous, or benign, liver lesions are common. Plays a vital role in immune function. All the patients underwent abdominal CT or MRI, all had splenomegaly, eight had hepatomegaly, and seven had intraabdominal lymphadenopathy. 4C), fungal microabscess, sarcoid, hemangioma, and infarctions [7]. Computed tomography displayed a hypoenhancing and hypodense lesion (Figure 1, A). Malignant mass lesions. Splenic lesions tend to be small or infiltrating and vary in size and configuration, making detection difficult, particularly without use of an organ-specific contrast agent. 34 Full PDFs related to this paper. 105-17B ). White arrow: Hypoechogenic lesion in spleen Interrupted arrow: The lesion has reverberation (=prolongation of sound; resonance) echophenomenon that have dorsal acoustic shadow (Spleen abscess). Splenic lesions are unusual cysts or inflamed areas of surface tissue on the spleen. There is no biliary dilatation. Typically, fungal microabscesses are 5 to 10 mm in size (almost all are smaller than 2 cm in diameter) and are seen as hypodense, ring-enhancing lesions (Figure 3, Figure 4). Applicable To. Pretreatment computed tomography (CT) image ( A ) shows a single well-circumscribed splenic hypodensity (arrow), a rarer presentation as compared with multiple splenic lesions. Fig. No other lymphadenopathy, extension or organ involvement was seen. Delayed contrast-enhanced helical CT scan displayed incomplete filling of hypodense splenic lesions. Occasionally the infarct may be multiple, resulting in poorly defined hypodense lesions. 3). D73.89 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. When the entire spleen is infarcted only rim enhancement of the capsule occurs from capsular vessels. Hypodense lesions are often seen on the spleen on CT images of the abdominal area. The authors present a series of selected cases to show the value of computed tomography (CT) and magnetic resonance (MR) imaging in depiction of splenic disease. White arrow: Hypodense lesion in the spleen without post-contrast saturation. It manifests as diffuse liver or spleen enlargement with multiple hypodense small masses scattered throughout the organ, ranging in size from 1 to 3 cm in CT scan. A less common finding is multiple, hypodense, hypovascular, 1-mm to 3-cm hepatic and splenic lesions on CT examination. Considering the CECT findings (i.e., splenomegaly and multiple splenic hypodense foci with ill-defined margins), the differential diagnosis included primary splenic lymphoma (PSL) or sarcoidosis . The purpose of this study was to analyse the sonographic findings of focal splenic lesions with an attempt to differentiate benign lesions from malignancies. Abdominal and chest CT scan confirmed ascites in addition to right axillary lymphadenopathy, scattered bilateral pulmonary nodular densities, a subcapsular 17.5 mm hypodense liver segment 4 lesion, and a 21 mm hypodense segment 1 lesion that was suspicious for neoplasm ( Figure 1 ), as well as bilateral cystic adnexal masses. Splenic infarction may be diffuse or focal. splenic lymphoma: commonest malignant tumor with splenic involvement 2. angiosarcoma of spleen: commonest primary malignant splenic tumor 3. haemagiopericytoma of spleen. In seven of ten patients, there were multiple hypodense nodular lesions superimposed to homogeneous parenchyma in the spleen (Figure 2 and 3) Also, two of them had nodular lesions in the liver. He/She will probably want to ⦠2C).On MR, the lesion was hypointense on the T1, ⦠Of the 53 cases, 30 cases (57%) were benign and 23 cases (43%) were malignant. Morphological factors must be applied in order to examine the appearance of the borders of the lesions or evaluate the abnormalities for calcification. liver abscesses. An algorithmic approach to splenic lesions according to their characteristic calcification patterns can therefore narrow the differential diagnosis and help guide management. Magnetic resonance imaging revealed a mildly hypointense and hypovascular lesion on T1- and T2-weighed images (Figure 1, B). The spleen is a relatively rare site for metastatic disease; patients with metastatic lesions in the spleen usually have disease in other sites as well. Post-contrast axial CT scan reveals multiple, hypodense lesions (arrows, b) in the spleen. Download full-size Figure 4: Axial section of contrast-enhanced CT scan of the abdomen 2 ). Hypodense lesions in the spleen suggested that the patient was not suffering from any abdominal tumor. Splenic abscess may be unilocular and represent bacterial etiology or can be multilocular which may be due to fungal or mycobacterial cause. The spleen had several lacerations extending to the surface from focal hypodense cyst-like lesions of the splenic parenchyma (Fig 1). Note the hypodense, oval-shaped lesion in the right lobe of the liver (asterisk) Full size image. Typically shows a hypoattenuating relatively well-defined intrasplenic lesion. Read Paper. The 2021 edition of ICD-10-CM D73.89 became effective on October 1, 2020. On USG (Figure 8A) it appears as low echogenicity lesion with complex internal echoes. Computed tomography showed floating membranes in the splenic cystic lesion (long arrow), rupture point (short arrow), and perisplenic fluid (open arrow). Splenic cyst is a rare condition, in which a cyst or a fluid filled sac may be formed in the spleen. Interventions: Given that it was uncertain whether it ⦠A few small, hypodense lesions in the spleen are consistent with metastatic disease. On CT, infarcts typically appear as sharply marginated, low-density wedge-shaped areas. During a follow-up visit two months later, a second CT unexpectedly showed not only an increase in the number and size of the hypodense lesions in the liver, but also the extension of lesions into the pancreas, the spleen and both kidneys (Fig. Introduction. A wide range of splenic lesions may be encountered in clinical practice. Infections are a typical cause of a spleen cyst. His serum was reactive for Varicella Zoster IgM. [2] [5] [9] Angiosarcoma is exceedingly rare; however, it is the most common primary malignant vascular tumor of the spleen. splenic metastases: 50% of which are from malignant melanoma. CECT is the imaging modality of choice for conditions affecting the spleen. The causes of hypodensity liver lesions are many and they could include benign liver cysts that have no symptoms or malignant tumors which are usually associated with certain symptoms. She responded well with anti- TB medication but required extended treatment duration of 24 months due to persistence of the splenic lesion on repeated CT scans. However, some ill-defined lesion ⦠Download PDF. The majority of splenic lesions are benign and when an incidental splenic lesion is found in an asymptomatic patient, it may pose a dilemma in workup because imaging findings are ⦠Splenic involvement by lymphoma has varied appearances including the spleen being normal that is microscopic involvement or splenomegaly with or without focal mass lesions [2, 3]. The most common benign primary neoplasm of the spleen is a hemangioma. A tuberculin skin test was positive at 20 mm. The spleen had several lacerations extending to the surface from focal hypodense cyst-like lesions of the splenic parenchyma (Fig 1). A Hypodense Liver Lesion or Hypodensity Liver is a deformity in the liver tissue that appears less dense than the surrounding tissue in radiological scans such as Computed Tomography (CT) scans or Magnetic Resonance Imaging (MRI). Lesions can be caused by many different illnesses and adverse health conditions, including bacterial and viral infections, abnormal buildups of immune cells, cancer, and direct physical trauma to the organ. CT-examinations were available in 15, in which splenic lesions all appeared hypodense (see Fig. This is the American ICD-10-CM version of D73.89 - other international versions of ICD-10 D73.89 may differ. Sometimes a part of the liver tissue may become hypodense as compared to the nearby tissue due to focal fatty changes or due to primary or secondary tumors. During a CT scan, this area will light up, but the finding of a hypodense mass does not necessarily indicate tumors or cancerous lesions. But in some cases, liver lesions are malignant (cancerous) and should be treated. In gray-scale ultrasound, multiple round lesions measuring 5â20 mm are scattered throughout the parenchyma of liver, spleen, and sometimes kidney (Video 4a). In patients with indolent lymphoma, hypodense lesions in the spleen should be biopsied to rule out transformation. An ultrasound-guided splenic core needle biopsy was performed, which led to the diagnosis of diffuse large B-cell lymphoma ( Figure 2 ). On CT, it is seen usually as a spherical hypodense (20 to 40HU) lesion with thick shaggy wall and However, because of the uncommonness of splenic disease, the spleen has been considered a âforgotten organ,â even though it is included and well demonstrated on abdominal images obtained with various imaging modalities. Enhancing lesion in the anterior bladder wall is also demonstrated. DDx: You get a CT abdomen for a patient and it reads, âInnumerable subcentimeter hypodense lesions are noted in the spleen. 1).Contrast-enhanced CT-images were available in three patients, with one lesion showing slight enhancement of the rim (no. 1. The contrast-enhanced image on the right shows a hypodense lesion with central calcification in the body of the pancreas and subtle enhancement of septations. The lesion is isodense to hypodense on plain CT and hypodense with mild enhancement on contrast enhanced CT similar to the present case. Liver lesions are abnormal clumps of cells in your liver, and they are very common. Should I be worried? I have read through your query in detail. The size of the cyst, the amount of pain the cyst is causing a ⦠Replacement of the liver and spleen with multiple hypodense lesions. Multiple hypodense, non-enhancing splenic lesions are a nonspecific finding seen in lymphoma, sarcoid, fungal microabscesses, and opportunistic infections. MR Imaging of the Spleen: Spectrum of Abnormalities. Although most hypodense lesions of the spleen can be considered benign, some findings and clinical conditions warrant closer attention to the lesion. Hypodense splenic lesions are frequently encountered on abdominal CT images. Fig. The splenic parenchyma was heterogeneous, and the splenic vein diameter was increased. There are several causes of splenic lesions, including cysts, organ trauma and sarcoidosis. In the right hepatic lobe, more inferiorly, there is a 1cm low-density lesion suggestive of a cyst. 7). Early in the evolution of the lesion its is similar to that of an abscess whereas more advanced lesions usually calcify. A wide range of splenic lesions may be encountered in clinical practice. 4). The usual differential diagnosis of multiple, focal lesions in liver and spleen include lymphoma, leukaemia deposits, metastasis, bacterial and fungal infection, and sarcoid. The purpose of this study was to analyse the sonographic findings of focal splenic lesions with an attempt to differentiate benign lesions from malignancies. Open Journal of Radiology, 2016. This mass does not appear to be a simple cyst. Littoral cell angioma of the spleen. The sonographic findings of 53 cases of verified focal splenic lesions, excluding post-traumatic haematomas and phleboliths, were retrospectively analysed. A contrast enhanced CT scan demonstrated multiple small hypodense nodules in liver and spleen. In twenty-three patients focal lesions of the spleen were described. Most hypodense splenic lesions on CT represent benign lesions that require no further work-up.
