A Case Report of Neuro-Behçet Syndrome: Frequent Neurological Manifestations Concurrent With Life-Threatening Illnesses.

​​​​Behçet disease (BD) is a recurrent, multisystemic autoimmune vasculitis that affects both small and large vessels. A combination of neurological signs and symptoms in BD is called neuro-Behçet syndrome (NBS). We present the case of a 31-year-old male diagnosed with chronic progressive NBS who presented with multiple relapsing episodes concurrent with infective endocarditis due to intravenous drug abuse, drug-induced hepatitis, acute kidney injury, and septic shock that is not related to BD.
