Hepatic angio-sarcoma: An unusual source of intra-hepatic bleeding.

INTRODUCTION

Hepatic angio-sarcoma represents an uncommon malignant tumor of the liver with a poor prognosis and a high rate of bleeding complications.

PRESENTATION OF CASE: We report a case of hepatic angio-sarcoma with a multi-nodular pattern complicated by intra-hepatic bleeding. The diagnosis was performed by computed tomography (CT). Angiographic procedure was unsuccessfully attempted as a treatment option. Autoptic examination confirmed the vascular nature of the malignant tumor.

DISCUSSION: Hepatic angio-sarcoma represents the most common malignant mesenchymal tumor of the liver. The diagnosis is provided by the histological examination and by specific endothelial markers. However, CT examination allows to recognize the disease and to detect intra-abdominal bleeding occurring in one-fourth of cases. Surgical resection represents the only definitive treatment of hepatic angio-sarcoma. In case of haemoperitoneum, trans-catheter arterial embolization represents the primary procedure used to stop the acute arterial bleeding.

CONCLUSION

CT represents the reference technique for the diagnosis of hepatic angio-sarcoma and allows to recognize the intra-abdominal bleeding which represents its most common complication. This condition always requires an immediate therapeutic approach.
