Abstract
Sylvian fissure lipomas are rare congenital malformations, with few cases reported in the literature. We present the case of a 28-year-old woman who consulted a neurologist for headache during pregnancy. Brain magnetic resonance imaging (MRI) showed bilateral extra-axial perisylvian lesions as an incidental finding. The MRI characteristics led to the diagnosis of bilateral Sylvian fissure lipomas with angiomatous component. To our knowledge, no previous cases of bilateral Sylvian fissure lipomas have been reported. This article provides an overview of the literature on Sylvian fissure lipomas, including their prevalence, pathophysiology, differential diagnosis, and management, to aid in their timely recognition and appropriate evaluation.
