Introduction: En plaque meningioma are a morphological subgroup of meningioma defined by a carpet or sheet-like lesion that infiltrates the dura and sometimes invades the bone. We present an exceptional case due to its localization and evolution.
Case: A 41-year-old female patient consulted for progressive swelling of the left frontoparietal region. CT-scan revealed thickening of the cranial medulla, without cerebral lesion. The tumor was removed. Histological analysis confirmed en plaque meningioma which recurred 7 years after.
Discussion: En plaque meningioma are a rare subtype of meningioma which rarely affects the skull vault. Relapse is frequent.
