Epitheloid haemangioendothelioma of liver: a vascular tumour easily mistaken for metastatic carcinoma on ultrasound imaging.

Epitheloid haemangioendothelioma is a rare neoplasm of vascular origin that may occur in the liver. Although there have been sporadic reports of this tumour in the past, the term “epitheloid haemangioendothelioma” was first suggested by Weiss and Enzinger only recently (Weiss & Enzinger, 1982). The tumour usually affects adults and pursues a relatively benign course intermediate between haemangioma and angiosarcoma; long-term survival with chemotherapy, hepatic resection and hepatic transplant has been documented. Scant reference can be found to its radiographic appearances. We present a case to illustrate the ultrasound appearances of this tumour and emphasize its potential confusion with metastatic disease. A 29-year-old woman presented with persistent right upper quadrant abdominal pain and anorexia over a period of 2 months. She had undergone laparotomy and repair of a liver laceration 16 years earlier, following a riding accident, but had been in good health in the intervening period.
