RÉSUMÉ
We report a patient diagnosed with neuro-Behcet's disease showing multiple enhancing lesions on a brain MRI that were confined to the cerebral cortex without any involvement of other brain regions. The patient, a 30-year-old man, was admitted because of seizure attacks. He had the symptom triad of recurrent oral ulcer, genital ulcer, and uveitis. Neurologic symptoms included ataxia, dysarthria, and dementia which had progressed over several years. During the hospital course, he underwent a right hemicolectomy due to bowel perforation. A pathological examination showed multiple discrete ulcerations from the cecum to the mid-transverse colon, consistent with Behcet's colitis. A brain MRI revealed multiple small enhancing lesions distributed over wide areas of the cerebral cortex. To our knowledge, this pattern of lesion distribution has not yet been reported in neuro-Behcet's disease.
