Other causes of thromboemboli in patients older than 40 years old may be thrombi that arise from the splenic artery or sinusoidal venous thrombosis in the setting of splenomegaly in the setting of leukemia, lymphoma, or sickle cell disease [14, 1922]. Radiographics. Among all splenic masses incidentally discovered on CT examination, approximately 1% of the masses were found to be metastatic in origin [1]. Multifocal lesions in the liver may appear as hypoattenuating lesions with rim enhancement and associated capsular retraction [46]. Associated findings with ovarian cancer or other metastatic cancers may include malignant ascites, peritoneal carcinomatosis, and omental cake [38] (Fig. 2014 Aug;49(8):524-31. doi: 10.1097/RLI.0000000000000050.

Ossification occurs in an estimated 20% of these and is more typically peripheral ( 11 ). With diligent diet and supplementation, you may be able to reverse the damage done and prevent . In cases in which splenic lesions on CT may not have a characteristic pattern of attenuation or enhancement, the morphologic features and pattern of calcifications can help the differential diagnosis [2]. Meanwhile, ringlike calcifications with splenic infiltration are characteristic of Pneumocystis carinii pneumonia resulting from fibrosis and calcification of the microabscesses with central caseating necrosis without preceding regression [3, 29, 30] (Fig. B, Coronal reconstruction of contrast-enhanced CT image shows multiple hypoattenuating masses of liver, with dominant mass showing coarse calcifications as described in A and smaller hypoattenuating, partially calcified mass in spleen. Appearance of lesion was most consistent with small cavernous hemangioma given its imaging characteristics. 10B 56-year-old woman showing no symptoms. The site is secure. It's a cutaneous condition characterized by calcification of the skin resulting from the deposition of calcium and phosphorus, occurring most frequently as one or a few skin lesions on the scalp or face of children. Calcified splenic granulomas are a common incidental finding, most commonly resulting from tuberculosis or histoplasmosis and less commonly from Pneumocystis carinii pneumonia or brucellosis [29, 30].

Hyperdense Lesions There are a variety of causes for lesions to be hyperdense (hyperattenuating) on CT scanning. Fig. This rare and interesting case demonstrates epiglottic cartilage calcification with no known underlying cause. Coronal T2-weighted MR image (E) shows internal increased signal intensity, which is consistent with fluid-filled daughter cysts, and loss of peripheral rim signal intensity, which is consistent with coarse calcifications and blooming artifact. It is a malignant vascular tumor that is usually multifocal with metastatic involvement of multiple other visceral organs and connective tissues [46]. Unlike other cysts, approximately 50% of pseudocysts show calcifications, whereas calcifications are rarer in true cysts. Additionally, the researchers discovered that symptomatic carotid lesion uptake of 18F-FDG was 27% higher than ipsilateral asymptomatic lesions . Whereas most calcified splenic lesions are presumed to be sequel-ae of prior granulomatous infection, there is a broader differential diagnosis for these lesions. AJR Am J Roentgenol. Semin Ultrasound CT MR, 2009. However, we can further define the location of the lesion by noting its relationship to the physis. Specifically, imaging procedures allow visualization of vesicular, colloidal, granular-nodular, and calcified phases of neurocysticercosis in the CNS (figure 2). 18(3): p. 67585; quiz 726.

The calcifications within hemangiomas can appear as central punctate, curvilinear, or speckled in areas of thrombosis [6, 9, 10]. Other common imaging features of lymphoma include splenomegaly and splenic infarcts [16, 44]. The diagnosis can be confirmed by serology tests and fine-needle aspiration cytology. show answer. Hydatid cysts can rupture either spontaneously or as a result of trauma, therefore the standard of treatment is spleen-conserving surgery when possible or total splenectomy [35]. For example, chest X-ray is familiar to everyone. Axial unenhanced CT image (A) in bone window shows hypoattenuating lesion in anterosuperior spleen with coarse calcifications. Check for errors and try again.

A wide variety of superficial soft-tissue masses may be seen in clinical practice, but a systematic approach can help achieve a definitive diagnosis or limit a differential diagnosis. Axial contrast-enhanced CT image shows septate, multilocular cystic mass with thin curvilinear calcifications and diffuse splenomegaly. Whereas most calcified splenic lesions are presumed to be sequel-ae of prior granulomatous infection, there is a broader differential diagnosis for these lesions. Smaller lesions may show flash-filling enhancement, especially among the capillary subtype, and larger lesions will often show centripetal progression of enhancement with a persistently enhancing central fibrous scar [6, 9, 11]. If present, the calcifications will be thin and curvilinear and along the peripheral wall or along the internal septations [8] (Fig. True epithelial cysts form during development with outer cuboidal epithelium and inner endothelium and result from infolding of peritoneal mesothelium within the spleen [13].
