Abstract

A 34-year-old male who had a hemangiopericytoma (HPC) within the trigone of right lateral ventricle presented with headache, disorientated consciousness and blurred vision. Computed tomography and magnetic resonance images revealed with homogenous contrast enhancement a 5 cm × 4.5 cm × 4.2 cm lesion within the trigone of right lateral ventricle. Angiographic study revealed a highly vascularized lesion fed from right anterior choroid artery anteriorly and right medial posterior choroid artery posteriorly. The tumor was grossly totally removed via right temporal gyrus. The immunohistochemical study was consistent with HPC. Differential diagnosis of HPC from meningioma and solitary fibrous tumor is crucial because of the high tendency of local recurrence and mestatasis of HPCs. Immunohistochemical study is a very valuable method to confirm the diagnosis of HPCs. Complete surgical resection and/or postoperative radiotherapy and/or radiosurgery were beneficial to long-term tumor control. Due to a prolonged time interval between surgery and local recurrence or metastasis, extensive follow-up to rule out local recurrences and delayed extracranial metastases is warranted.
