This paper reports a case of malignant liver hemangiopericytoma broken after an abdominal traumatism which revealed that the patient has this disease. This case is interesting because the abdominal traumatism gave us the opportunity of making a precocious diagnosis. The clinical and paraclinical signs of acute abdomen fastened surgery. The paper reviews the medical literature linked to these rare tumors. The paper also describes morphological features typical for these vascular tumors, whose evolution is unpredictable.

Hemangiopericytoma (HP) is a vascular tumor that mostly develops in soft tissues. The greater omentum is a very rare site for its occurrence. We present herein the clinical evaluation and outcome of a very rare case of HP that caused acute abdomen. We evaluated a case of acute abdomen due to rupture of a HP of the greater omentum. The clinical and laboratory findings and treatment modality are reported. A 70-year-old patient with severe abdominal pain was operated with the diagnosis of acute abdomen. A semi-solid mass (12 x 10 x 6 cm) originating from the greater omentum was detected during surgery. There was active bleeding from the tumor. Pathologic evaluation of this lesion was reported as benign HP. HP of the greater omentum can be the cause of intraabdominal bleeding leading to acute abdomen. Surgical resection is the treatment of choice, especially in benign hemangiopericytomas.
