Objective We aimed to identify conditions mimicking nervous system involvement among patients with Behçet's syndrome (BS) and to determine clinical, laboratory and imaging findings that may help in the differential diagnosis.

Background BS patients who present with signs and symptoms related to the nervous system are usually referred to neurology, but only a minority of these patients meet the criteria for NeuroBS.

Design/Methods We screened the charts of 500 consecutive BS patients to identify those who were referred to neurology at any time during their follow-up. The final diagnoses, presenting signs and symptoms, laboratory and imaging results were retrieved from patient charts. Patients who did not have a follow-up visit during the last 3 months were invited to the clinic.

Results Among the 500 BS patients, 116 (23%) had been referred to neurology. Among these, 29 (5.8%) were diagnosed with typical central nervous system involvement of BS (NeuroBS). The type of NeuroBS was parenchymal involvement in 21 patients, cerebral venous sinus thrombosis in 7 patients, and both in 1 patient. 30 patients (6%) had other conditions related to the nervous system, 46 (9.2%) did not have a nervous system disorder, and their symptoms recovered spontaneously, and 11 (2.2%) were lost to follow-up without a definite diagnosis. Of the 30 BS patients who were diagnosed with another nervous system condition, 14 (46%) had primary headache syndromes, 6 (20%) had psychiatric disorders, 2 had entrapment neuropathy, and 1 each had epilepsy, glial tumor, multiple sclerosis, Meniere's disease, optic neuritis, neuroretinitis, steroid myopathy and polyneuropathy.

Conclusions Nervous system conditions other than NeuroBS are frequent among BS patients referred to neurology. Caution is required to avoid misdiagnosis of these patients as NeuroBS
