Axial contrast-enhanced CT image of abdomen shows low-attenuation mass in spleen with stippled internal calcifications and diffusely increased attenuation of intraperitoneal ascites, consistent with peritoneal carcinomatosis. The larger lesions were cystic and filled with material ranging from a cheesy solid to turbid fluid ( Fig 3 ). Some lesions may have coarse central calcifications in a radial pattern as a result of underlying fibrosis [ 52 ]. Pseudocysts, or false cysts [3], make up 80% of all splenic cystic lesions [10].

A trichilemmal cyst, also known as pilar tumor, is a common cyst that forms from a hair follicle. 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]. Splenic hemangiomas are usually small and exhibit slow growth related to nonencapsulated proliferations of blood vessels [5, 9].
