Meningiomatosis, the Experience of the “Marie Curie” Medical Clinic on a Case

Abstract

Meningiomatosis or multiple meningiomas are defined by the presence of at least two meningiomas. A meningioma is an extra-axial tumor that develops from the meninges more precisely at the level of the arachnoid. Its multiple characters is encountered in 1-9% of cases, with a female predominance due to hormonal factors, exposure to ionizing radiation and very rare in children. It is most often located at the supra tentorial level intra cranially. We report a case of aggressive cerebral Meningiomatosis diagnosed in the radiology department of the ''Marie Curie'' Medical Clinic in Bamako-Mali with the aim of describing and recalling the radiological characteristics of multiple meningiomas on Magnetic Resonance Imaging (MRI). It was a young male subject aged 10 years referred for intracranial expansive process. MRI exploration revealed multiple meningiomas (occipital convexity, bilateral temporal and jugum sphenoid). The pathology study confirmed cerebral Meningiomatosis. MRI remains the reference examination in the management of cerebral Meningiomatosis.
