Purpose. To illustrate the propensity of meningeal hemangiopericytoma to spread extraneurally, as a distinction to the ordinary meningioma.Patients or subjects. A patient with long history of meningeal hemangiopericytoma was reported.Methods. A case report on meningeal hemangiopericytoma with a literature review was presented.Results. The patient has multiple local recurrence as well as distant...

intracranial hemangiopericytomas (hpc) are rare vascular tumors. they account for 0.4% of primary central nervous system tumors. hpc is more commonly located supratentorially and tends to occur in a younger age group, with average age at presentation of 38–42 years. the tumor was found throughout the entire cns, usually superficially and closely related to the meninges. moreover, they have a st...

BACKGROUND Meningeal hemangiopericytoma is a rare, aggressive CNS tumor that tends to invade locally, metastasize, and has a high rate of recurrence. HIV classically increases the risk of 3 AIDS-defining malignancies: Kaposi's sarcoma, non-Hodgkin's lymphoma and invasive cervical cancer. More recently, considerable interest has been paid to the link between HIV and a wider range of non-AIDS-def...

Aims. We report on the unusual case of a 43-year-old man who developed recurrent meningeal hemangiopericytoma and presented with hypoglycemia 6 years after excision of the tumor. Methods and Results. We utilized computed tomography to assure multiple tumor metastasis and cranial recurrence of previous meningeal hemangiopericytoma and clinical laboratory tests and immunohistochemical staining to...

Intracranial hemangiopericytomas (HPC) are rare vascular tumors. They account for 0.4% of primary central nervous system tumors. HPC is more commonly located supratentorially and tends to occur in a younger age group, with average age at presentation of 38–42 years. The tumor was found throughout the entire CNS, usually superficially and closely related to the meninges. Moreover, they have a st...

Background: Solitary fibrous tumor / hemangiopericytoma (SFT HPC) and fibroblastic types of meningioma have similarities that is difficult to distinguish based on histology. Immunohistochemistry STAT6 SSTR2A are definitive biomarkers in both tumors. Inversion-mediated fusions between two genes, NAB2 STAT6, were detected SFT HPC inducES proliferation cells. The somatostatin receptor (SSTR) 2 loc...

Meningeal hemangiopericytoma (HPC) is a rare tumor in the central nervous system. It is often reported as “Meningioma”. Unlike meningiomas, HPC has a high rate of local recurrence and distant metastasis, which may occur several years after initial treatment [1]. The purpose of this article is to report a case of parasagittal hemangiopericytoma with delayed multiple extracranial metastases and l...

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 ...

Mesenchymal tumors in the liver, whether primary or metastatic, are rare. Meningeal hemangiopericytoma (HPC) is characteristically associated with delayed metastasis and the liver is one of the most common sites. Despite its consistent histological features, a pathological diagnosis of HPC in the liver is sometimes not straightforward due to its rarity and usually remote medical history of the ...
