An unusual case of neurobrucellosis presenting with unilateral abducens nerve palsy: clinical and MRI findings.

Brucellosis is an endemic zoonotic disease in which neurobrucellosis occurs in 5-10% of cases. Variable clinical and radiological manifestations of neurobrucellosis can mimic those of other diseases. In this report, we present unusual clinical and magnetic resonance imaging (MRI) findings in a patient with neurobrucellosis and unilateral abducens nerve palsy. Her MRI showed punctate leptomeningeal enhancement of the cerebellum on contrast-enhanced T1-weighted images, and a focal area of hyperintensity in the splenium of the corpus callosum on T2-weighted images.
