Cerebral Leptomeningeal Angiomatosis CT and MRI evaluation

Abstract

Leptomeningeal angiomatosis is an uncommon benign hamartomatous lesion usually involving the leptomeninges with or without cerebral cortex involvement.

Three middle-aged patients with seizures from adulthood had undergone CT and MRI examinations and craniotomies which revealed leptomeningeal angiomatosis. Another two young patients with Sturge-Weber syndrome and leptomeningeal angiomatosis were also evaluated.

MRI is clearly helpful in establishing the topography and vascular malformative nature of the lesion, while CT is more accurate in detecting vascular calcifications.
