Some cysts may have internal septations that enhance with contrast administration [10]. Disseminated Pneumocystis carinii pneumonia may additionally present with punctate calcifications in the adrenal glands and pleural or peritoneal effusions that subsequently calcify [12, 29]. Approximately 5060% of patients with these neoplasms have gain-of-function mutations in the Janus kinase 2 gene (JAK2) [53, 54]. Complete resection followed by irradiation and chemotherapy achieves 88% survival at 5 years. Four cases of calcification were noted on CT in 38 consecutive bladder scans (10.5%). 203(6): p. 1192204.

The main consideration for differential diagnosis is a hemangioma, which is best ruled out in favor of angiosarcoma with evidence of metastatic disease [52]. On T2-weighted MR images, regenerative nodules typically appear hypointense, whereas HCC classically appears moderately hyperintense [4]. Splenic lesions may also reflect benign systemic abnormalities such as disseminated granulomatous infection or underlying portal venous congestion. This mass was most consistent with epidermoid squamous cyst given its imaging characteristics. Because Thorotrast has a half-life of 22 years, it has great radioactive potential, leading to fibrosis and carcinogenesis, and may eventually lead to malignancy in patients up to 65 years after injection, especially in the liver and spleen because of the biodistribution and clearance [36].

A chronic hematoma may result in the formation of a posttraumatic pseudocyst that commonly has peripheral curvilinear calcifications (Fig. They have only minimal internal vascularity and can have peripheral serpiginous enhancement. Other CT findings in sickle cell disease include hepatic hemosiderosis resulting from transfusional iron overload, extramedullary hematopoiesis, cardiomegaly, vertebral endplate infarcts, osteonecrosis or osteomyelitis, and cholelithiasis resulting from hemolysis with pigmented gallstones [24, 25]. Diameter 6 cm! The use of 18F-FDG PET imaging to evaluate plaque vulnerability and the risk of associated ischemia episodes has been supported by some evidence from other research [ 166 ]. When compared with pseudocysts, which are the primary differential diagnostic consideration for these lesions, true epithelial cysts are more likely to have internal enhancing septations but are less likely to have wall calcifications [14]. The typical appearance is a hypoattenuating lesion with occasional calcifications and mild enhancement [38], which may be associated with splenomegaly [40]. Subepidermal calcified nodule is a type of Calcinosis cutis. Radiologists must be familiar with the appearances of common scalp lesions to reach an accurate diagnosis.
