Meningoradikulitis

Imaging in

Lyme neuroborreliosis. Meningoradiculitis due to Lyme neuroborreliosis (LNB) in a 73-year-old female. She experienced periods of strong superficial abdominal pain, reduced appetite and headache. Sagittal T2 (a) and T1 after gadolinium-based contrast agent injection (b, c) demonstrated normal cord parenchyma and diffuse leptomeningeal enhancement (arrows) of spinal cord and brain stem. Cerebrospinal fluid (CSF) analysis showed pleocytosis and intrathecal production of Borrelia burgdorferi (Bb)-specific IgM and IgG antibodies. No leptomeningeal enhancement was found 4 weeks after the treatment on post-contrast sagittal T1 weighted images (d, e)
