Haemangiopericytoma diagnosed from a metastasis 11years after surgery for "atypical meningioma".

Abstract

  • Meningeal haemangiopericytoma (HPC) is a rare tumour often mistakenly reported as "vascular meningioma". Unlike meningiomas, HPC has a high rate of local recurrence and distant metastases, which may occur several years after initial treatment. We report a patient in whom a HPC was misdiagnosed as benign vascular meningioma and the patient discharged from follow-up. HPC was diagnosed 11 years later from biopsy of a skeletal metastasis. Histological review of the meningeal tumour confirmed the diagnosis of meningeal HPC. Meningeal HPCs resemble meningiomas clinically, radiologically and even light microscopically. As a result, they can be reported as atypical meningioma, as in this case. HPC's are more aggressive than typical meningiomas, with a high rate of recurrence and distant metastasis, often late in the course of the disease. Management of meningeal HPC differs from that of typical meningioma, with a need for post-operative radiotherapy and long-term follow-up.
