Duplicated middle cerebral artery origin with an aneurysm.

Abstract Middle cerebral artery (MCA) anomalies are relatively rare and often related to aneurysms. Familiarity with these anomalies is important in resolving problems that arise in the complex angioarchitecture. Reports often describe that aneurysms that are related to accessory or duplicated MCA are often located at its origin.

AB  - RATIONALE: Middle cerebral artery (MCA) anomalies are relatively rare and often
      related to aneurysms. Familiarity with these anomalies is important in resolving 
      problems that arise in the complex angioarchitecture. Reports often describe that
      aneurysms that are related to accessory or duplicated MCA are often located at
      its origin. PATIENT CONCERNS: A 59-year-old man presented with a headache for 10 
      days, without nausea and vomiting. The physical examination was negative.
      DIAGNOSIS: A computed tomography (CT) scan revealed an intracerebral hematoma in 
      the deep right frontal lobe, near the caudate nucleus. Digital subtraction
      angiography (DSA) revealed an anomalous duplicated origin of the right MCA, with 
      occlusion of the main MCA trunk as well as twisting and dilation of the accessory
      MCA trunk. A wide-necked aneurysm was located at a sharp curve of the tortuous
      accessory MCA trunk. A ruptured aneurysm related to a duplicated MCA origin was
      diagnosed. INTERVENTIONS: Open surgery was rejected by the patient; hence,
      palliative endovascular coil embolization of the larger daughter sac was
      performed. OUTCOMES: The postoperative course was uneventful. There was no
      rebleeding at 8-months follow-up. LESSONS: MCA anomalies are relatively rare and 
      often related to aneurysms. It is important to be familiar with these anomalies
      as related lesions often manifest within a complex angioarchitecture. Aneurysms
      at the trunk of an anomalous MCA are a rare entity and open surgery may be
      recommended.
