✦ Synopsis

Littoral cell angioma (LCA) is a rare benign vascular tumor of the spleen with characteristic histomorphologic features. Only a few descriptions of the radiologic appearance of this tumor have been published, and those descriptions are variable. We report a case of LCA in a 37-year-old man with psoriasis and nonspecific symptoms of weakness, pain and fatigue, normocytic anemia, and thrombocytopenia. The results of abdominal sonography and contrast-enhanced CT correlated: the 2 modalities revealed hepatosplenomegaly and multiple round splenic lesions of similar appearance and size (on sonograms, ill-defined echogenic lesions up to 3.2 cm without acoustic enhancement; on CT scans, hypodense, nonenhancing lesions up to 3.5 cm). Because making a differential diagnosis was difficult and our presumptive diagnosis was hemangioma or lymphoma, splenectomy was performed. Postoperative pathologic examinations confirmed a final diagnosis of LCA. The patient's recovery was uneventful. LCA should be considered when making a differential diagnosis of splenic lesions, and sonography may be more helpful than CT in reaching a diagnosis of LCA.
