Abstract
Introduction: Hemangiopericytomas of the central nervous system are rare and represent less than 1% of intracranial tumours. They arise in Zimmerman’s pericytes. Their radiological appearance can be misleading and lead to a false diagnosis of meningioma. The diagnosis is histological and immunohistochemical.
Objectives: Describe the anatomoclinical, radiological, therapeutic and evolutionary aspects of meningeal hemangiopericytomas.
Materials and methods: Retrospective study from 2001 to 2018 on 07 cases of intracranial hemangiopericytomas treated in the radiotherapy department of the National Institute of Oncology in Rabat.
Results: The average consultation period was 10.2 months ± 2.42. The average age of the patients was 53 years ± 8.61. The main clinical features were intracranial hypertension signs, visual acuity decrease (03 cases), hemiplegia (01 case), gait disorder (01 case), balance disorders (01 case) and diplopia (01 case).
Conclusion: Hemangiopericytoma is a very rare vascular tumour; its diagnosis can be difficult and mistaken for a meningioma; the imaging is not very specific; the diagnosis of certainty remains anatomo-pathological and is based on histology and immunohistochemistry.
