Background: Intracranial meningeal hemangiopericytoma is a rare entity and exhibits a sarcomatouslike neoplasm. Hemangiopericytoma is usually misdiagnosed as meningiomas clinically because of the similar location and images. Unlike meningiomas, hemangiopericytoma has a propensity of local recurrence and extracranial metastasis. Early diagnosis and complete resection of tumor remain a challenge for neurosurgeons.
Case Report: A 53-year-old female complained of weakness over right side limbs and unstable gait for nearly about 2 months before admission. Computed tomographic scan and magnetic resonance images of brain revealed a huge tumor with peritumoral edema over left parieto-occipital region, compressing the lateral ventricle. Near total resection of tumor was performed later. The pathology confi rmed the diagnosis of hemangiopericytoma. Previous neurological deficits recovered well and postoperative radiotherapy was also administrated.
Conclusions: Intracranial meningeal hemangiopericytoma should be listed in the differential diagnosis of intracranial extra-axial cerebral tumors.
