Littoral cell angioma: a vascular tumor mimicking a solid tumor on a Tc-99m-red blood cell spleen scan.

Abstract

A splenic space occupying lesion, in a 45-year-old woman, was negative in a Tc-99m-RBC spleen scan. A diagnostic splenectomy was performed and the lesion was found to be a vascular tumor, lately identified as littoral cell angioma. The histological and immunohistochemical findings are discussed in correlation with the imaging results.
