Abstract

Progressive myelopathy, urinary retention and gait problems are rare presenting features of Lyme neuroborreliosis. A 30-year-old man had 11 months of urinary retention and 3 months of spastic paraparesis. MR scans of the brain and the spinal cord showed leptomeningeal thickening with contrast enhancement. Cerebrospinal fluid showed mononuclear pleocytosis, decreased glucose, increased protein and chemokine ligand 13, with intrathecal Borrelia-specific IgM and IgG antibodies. He received 14 days of intravenous ceftriaxone followed by 14 days of oral doxycycline. Despite improvement at 6 months, he still had severe gait problems. Urinary retention in otherwise healthy people needs investigation, and Lyme neuroborreliosis is a rare cause.
