BACKGROUND The hemangiopericytoma is an uncommon vascular tumour. We report a case of interest because of its rarity, size and location. CASE REPORT We present the case of a 63-year-old woman who consulted for abdominal pain. TAC, MRI and arteriography showed a pelvic mass occupying Douglas' space, displacing the uterus, bladder and sigma, with vascularisation relative to the inferior mesente...

Meningeal hemangiopericytomas are rare vascular tumors that have a propensity for recurrence and metastasis. Intracranial hemangiopericytomas are rare vascular tumors. They account for 0.5% of primary central nervous system tumors and 2% of meningiomas. Unlike usual benign meningiomas, which rarely metastasize extracranially, meningeal hemangiopericytoma has a high rate of local recurrence and ...

BACKGROUND The distinction between meningioma, schwannoma and solitary fibrous tumour/ hemangiopericytoma can be challenging in some cases. This study evaluates the expression of Somatostatin receptor 2A (SSTR2A) and Claudin-1 in these different tumours. MATERIAL AND METHODS Thirty-five cases of meningioma, 10 cases of intracranial schwannoma and 10 cases of hemangiopericytoma were assessed. ...
