title: Non-moyamoya bilateral middle cerebral artery agenesis mimicking multiple sclerosis.
abstract: We present a case of a 41-year-old woman who carried the misdiagnosis of multiple sclerosis for 13 years while on disease modifying therapy [DMT]. Her neurologic work-up showed an extremely rare type of bilateral middle cerebral arteryocclusive disease, a basilar apex aneurysm and paroxysmal atrial fibrillation. A thorough search for alternative neurologic diagnosis is recommended before patients are given a definitive diagnosis and committed to DMT.
