Aneurysms are usually less than 2 cm in diameter [56]. Exposure to thorium dioxide (Thorotrast) is the most common iatrogenic cause of hepatic angiosarcoma and it can also cause splenic angiosarcoma. 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]. J Gastrointest Surg. An understanding of the scalp's anatomy is essential for topographic characterization of a lesion as the first step for a differential diagnosis; not only the imaging appearance, but also the lesion's location, the clinical history, and the patient's age should be considered when evaluating a mass of the scalp. Accurate characterization of calcium distribution and morphology is key to successful treatment.

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]. The most common malignancy in the spleen is lymphoma, with the spleen being one of the most commonly involved organs; however, it is rarely the only affected organ [1]. Before Lesions will be hyperintense on T1- and T2-weighted imaging because of hemosiderin [2]. Determining the cause of splenic lesions is essential to guide appropriate management; the pattern of calcification together with other imaging and clinical findings can aid with differentiation.
