[Rare differential diagnosis on suspected liver tumor].

This case report describes a 77-year old woman with a leiomyosarcoma of subhepatic inferior caval vein. The presented symptom was unspecific abdominal pain. Ultrasound and CT suggested a primary liver tumor. MRI revealed retroperitoneal location of the neoplasm. The tumor was resected completely and ICV was replaced by a PTF-graft. Vascular leiomyosarcoma is a rare tumor entity, which often is diagnosed in advanced stage. Depending on location it can be mistaken for neoplasms of other organs.
