Primary angiosarcoma of the spleen: In vivo and in vitro MRI findings

Primary splenic angiosarcomas are extremely rare rumors with very poor prog nosis. These tumors, highly aggressive and lethal, present with widespread metastatic disease or splenic ruptures. The possibility to lengthen the sur vival by splenectomy before the development of splenic rapture makes an ear ly radiological diagnosis a necessity. Multimodality imaging findings of a patient with splenic angiosarcoma is presented. In vivo and in vitro magnet ic resonance imaging (MRI) features of the spleen are compared to macro- an d micropathological findings. (C) 2001 Elsevier Science Inc. All rights res erved.
