Retroperitoneal malignant fibrous histiocytoma: the angiographic and computed tomographic features of an unusual tumor
Abstract
Malignant fibrous histiocytomas are uncommon retroperitoneal soft tissue tumors. We report a case of a malignant fibrous histiocytoma of the retroperitoneum that was anmgiographically hypervascular and indistinguishable from renal cell carcinoma. Computerized tomography of the abdomen demonstrated extensive psoas muscle infiltration by tumor. This feature may be useful in differentiating a renal cell carcinoma from a primary retroperitoneal sarcoma.
