MR Imaging of Meningioangiomatosis in a Pediatric Population

Meningioangiomatosis (MA) is a rare intracranial hamartomatous lesion. We retrospectively reviewed the MRIs in 6 pediatric patients with a histopathologic diagnosis of MA. Patients with MA demonstrated a solitary lesion in the frontotemporal regions, with FLAIR hyperintensity and leptomeningeal enhancement. A solitary brain lesion in the frontotemporal lobes associated with leptomeningeal enhancement and T2/FLAIR hyperintensity should include the possibility of MA in a pediatric patient who presents with seizures or headaches.
