[5, 6]. This series demonstrates the spectrum of radiologic findings and provides new evidence as to the pathogenesis of false cysts. Materials and MethodsFor 52 cases of nonneoplastic, nonparasitic splenic cysts with radiographs in the files of the Registry of Radiologic Pathology at the AFIP, clinical data were derived from summaries submitted by the case contributors.All diagnoses were confirmed by review of both gross and histologic data by the Department of Hematologic Pathology. The cysts were categorized as either "true' or "false.

Ten cases of hemangioma of the spleen were reviewed. Plain abdominal radiographs and scintigrams are helpful in specifying the splenic location. Calcification, either central punctate or peripheral curvilinear, can be detected on radiographs or computed tomographic (CT) scans. The spectrum form solid to cystic change observed in the pathologic specimens is reflected in analogous patterns on CT scans and sonograms: predominantly solid mass; mass with cystic spaces. The angiographic findings are nonspecific. It is possible to suggest the diagnosis of hemangioma of the spleen when an asymptomatic patient presents with a discrete splenic mass, particularly if there is evidence of calcification and cystic change within the lesion.
