We report a retrospective analysis of 15 cases of neurobrucellosis. Initial clinical manifiestations consisted of meningoencephalitis in 5 patients, acute and subacute meningitis in 4, intracranial hypertension in 2, polyradiculoneuritis with albumin-cell dissociation in 2 (one with cerebral and subarachnoid hemorrhage), and transverse myelitis and lumbar epidural abcess with root involvement in 1 each. Cranial nerve involvement was noted in 5 patients. Fever was absent in 3. Transient clinical manifestations mimicking transient ischemic attacks were noted in 3 patients. Unusual central nervous system demyelinating lesions were observed on the MRI in 1 of the patients with meningoencephalitis. Cerebrospinal fluid Wright titers and culture were rarely helpful. Most patients responded favorabely with minor neurological sequelae. The most commonly used antibiotics were rifampin, doxycycline, and trimethoprim-sulphamethoxazole, in various combinations for at least 3 months. The differential diagnosis of neurobrucellosis is wide. However, in endemic areas, the disease should be ruled out in all patients who develop unexplained neurological symptoms.
