Leptomeningeal Enhancement As A Sole Magnetic Resonance Imaging Finding of Secondary Central Nervous System Vasculitis: A Case Report

Abstract

The main radiological findings of central nervous system (CNS) consist of multiple subcortical infarcts, parenchymal and leptomeningeal enhancement, petechial hemorrhages on MRI and multifocal caliber changes of the vessels on MRA and DSA. Solely or prominent leptomeningeal enhancement is rarely seen as an isolated manifestation of CNS. We report a case of intracerebral vasculitis secondary to inflammatory bowel disease (IBD) showing leptomeningeal enhancement as a unique finding in routine contrast-enhanced cranial MRI and aimed to emphasize the importance of these finding in diagnosing CNS.
