This is the report of a 32-year-old man with Behçet’s disease described dizziness, double vision and headache. The cranial MRI demonstrated a ring enhancing nodular lesion in left medial occipital lobe, and T2 hyperintense lesion in diencephalon mimicking abscesses. A stereotactic biopsy was performed. The histology showed features of neuro-Behçet’s disease and an abscess was ruled out. During the procedure till the histopathologic results were gathered he was given ceftriaxone and metronidazole when cerebellar signs appeared. Cranial MRI showed additional symmetrical hyperintensities in bilateral cerebellar dentate nuclei which was attributed to metronidazole toxicity. Repeat MRI performed forty days later showed complete resolution of both dentate hyperintensities and diencephalic and occipital ring enhancing lesions. This is the first case of neuro-Behcet’s disease complicated by metronidazoleinduced encephalopathy. This case also showed that nodular ring enhancing lesions can be seen in neuro-Behçet’s disease and can lead to difficulties in diagnosis and management.
