Hemangiopericytomas were first described as a unique entity by Stout and Murray in 1942 [ 1 ]. Behavior is variable, and these tumors can metastasize early or late. We recently encountered a hemangiopericytoma metastatic to the lungs 20 years after its initial resection from the mandible.

Background: Intracranial hemangiopericytomas (HPC) and solitary fibrous tumors (SFTs) (HPC-SFT) are rare vascular tumors that resemble meningioma on imaging and predominantly affect young adults. HPC-SFT have a high rate of local recurrence with well-known propensity for extracranial metastases.

2007-06-06 A meningeal hemangiopericytoma (MHPC) is an aggressive tumor characterized by a high rate of local recurrence and late distant metastasis. The objective of this study was to share our experience with the treatment of a MHPC and how to distinguish this tumor from a meningioma. BACKGROUND: Intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC) often shows extracranial metastasis, and treatment options are very limited. Immune-checkpoint molecules have not been studied well in SFT/HPCs, and their role in intracranial SFT/HPCs remains unclear. 1998-09-01 Intracranial meningeal hemangiopericytoma: Recurrences at the initial and distant intracranial sites and extraneural metastases to multiple organs. Mol Clin Oncol. 2015 Jul;3 (4):770-774.

Abstract: This report describes the clinical features, diagnostic and treatment modalities of a 62-year-old female patient with liver metastasis and local recurrence of meningeal hemangiopericytoma (HPC), who presented with the clinical manifestations of memory deterioration, visual reduction and abdominal mass for one month. hemangiopericytoma with bone metastasis. Three of them had been previously misdiagnosed as meningiomas and were amended to hemangiopericytomas only when the bone me-tastasis occurred. The authors investigated the clinical and radiological features and the treatment strategy for bone metastasis from a rare tumor, intracranial meningeal hemangiopericytoma.

Hemangiopericytoma is a neoplasm that commonly manifests as an intracranial mass lesion.[] According to the 2007 World Health Organization classification, it is a “tumour of the meninges”[] and constitutes approximately 2% of all such tumors.[8 9] Hemangiopericytoma is a clinically malignant tumor due to its high incidence of local recurrence and extraneural metastasis, which eventually She had a voluminous hepatic metastasis and multiple small lung metastases from a meningeal hemangiopericytoma initially operated on 11 years earlier. High blood levels of an abnormal form of insulin‐like growth factor type 2 (IGF II) associated with low blood levels of insulin, growth hormone, IGF I, and IGF BP3 were observed. Spinal hemangiopericytoma is a rare neoplasm that behaves similar to intracranial hemangiopericytoma, with approximately 140 cases being reported in the literature. We report a case of recurrent hemangiopericytoma of dorsal spine in a 55-year-old women treated with surgery for 3 times, with liver metastasis.
