The typical appearance is a hypoattenuating lesion with occasional calcifications and mild enhancement [38], which may be associated with splenomegaly [40]. True epithelial cysts present incidentally and are generally asymptomatic; they are also called benign epithelial cysts [12]. Imaging may show a solitary mass, multiple splenic masses, or diffuse splenic involvement with splenomegaly. Causes may include atherosclerosis, portal hypertension, trauma, or pancreatitis [39, 57]. Patients generally show no symptoms, but when the hemangiomas are large, rupture can occur in up to 25% of cases [48]. Gamna-Gandy bodies are asymptomatic nodules that affect 912% of patients with portal hypertension and that occur as a result of the deposition of hemosiderin [3, 16]. 5C). Complete resection followed by irradiation and chemotherapy achieves 88% survival at 5 years. Calcification of the Arteries - There are many different ways that calcification can occur: High vegetable oil intake, blood thinning medications, high fluoride intake, vitamin C deficiency, a high calcium intake without adequate magnesium, K and D, and excessive vitamin D to low vitamin K intake. Some lesions may have coarse central calcifications in a radial pattern as a result of underlying fibrosis [52]. AJR Am J Roentgenol. B, 64-year-old woman who presented with hepatic angiosarcoma and prior exposure to thorium dioxide (Thorotrast).

In dermatomyositis, the most prominent calcifications . When the microabscesses heal, they may calcify with or without preceding regression. A calcified or ossified mass in this location is exceedingly rare, but a calcified variant of pleomorphic adenoma has been reported. Nine . The main consideration for differential diagnosis is a hemangioma, which is best ruled out in favor of angiosarcoma with evidence of metastatic disease [52].
