Neurobrucellosis: a rare cause for spastic paraparesis

ABSTRACT

A 41 year old man presented to the outpatient department with a three month history of difficulty in walking. He also had a history of positive sensory symptoms in the form of pins and needle sensation mostly below the waist. His symptoms had been progressive and there was no significant family history. He demonstrated a spastic gait and could only walk with assistance and support. DTR were hypertonic and sensory deficit was observed below twelfth dorsal vertebra. Sphincter abnormalities were present. Plantars were extensor bilaterally. Cerebral and spinal MRI with contrast was unremarkable. Brucella antigen titers were significantly high. CSF report was consistent with neurobrucellosis. After detailed analysis of his history, clinical picture and investigations the diagnosis of neurobrucellosis was made. Combined antimicrobial therapy was started, his neurologic condition gradually improved and he was able to walk without help after three months of treatment. Hence this case showed that neurobrucellosis may present as acquired progressive spastic paraparesis and it should always be borne in mind in patients with spastic paraparesis.
