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.

Intracranial hemangiopericytoma (HPC) is a rare brain tumor with aggressive biologic behavior associ-ated with high recurrence rate and often with extracranial metastasis. The most common sites of ex-tracranial metastasis of the intracranial HPC are the long bones, lung, liver and abdominal cavity in the order of frequencies.

The overall reported extracranial metastasis rates vary from 2.6% to 56%. 7,13,15,18,19,26,27,35 Our extracranial metastatic rate was 10%. Guthrie et al. reported that the development of extracranial metastasis results in a significantly reduced survival period. 14 In Canine hemangiopericytoma: an evaluation of metastatic potential E. Handharyani, K. Ochiai, T. Kadosawa, T. Kimura, T. Umemura Canine hemangiopericytoma is a common soft tissue neo-plasm in the subcutis of dogs.20 The neoplasm is locally in-ﬁltrative and occasionally recurs although the tumor seldom metastasizes. However, the majority of meningeal hemangiopericytoma can eventually metastasize elsewhere in body.

Hemangiopericytoma is a term used to described a group of tumors that are derived from pericytes, the cells normally arranged along specific types of blood vessels called capillaries and venules. These types of tumors are typically slow-growing, may be either benign (non-cancerous) or malignant (cancerous), and may occur anywhere in the body.

Therefore, the tumor was diagnosed as a metastatic hemangiopericytoma with malignant potential. Careful long-term follow-up is required because metastases can develop after an extended disease-free interval.

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. Therefore, the tumor was diagnosed as a metastatic hemangiopericytoma with malignant potential.

Meningeal/intracranial SFT/HPCs (icSFT/HPC) have a poor clinical outcome with metastatic behavior compared to soft tissue/extracranial SFT/HPCs (exSFT/HPC), but the underlying genetic factors are unclear.
