“…To the best of our knowledge, 33 cases of aneurysm originating from a DMCA have been reported to date [ 10 , 11 , 12 , 13 , 14 , 15 ]. Aneurysms in this location are rare and frequently present as a subarachnoid haemorrhage despite their small size.…”

A duplicated middle cerebral artery (DMCA) is a common anomaly. However, aneurysms arising from the origin of a DMCA are extremely rare. A 22-year-old female was admitted to our hospital with a World Federation of Neurosurgical Societies grade 2 subarachnoid haemorrhage. Four-vessel angiography revealed a DMCA and an aneurysm arising from the origin of this artery. The aneurysm was successfully treated by embolization, and the patient was discharged 2 weeks later. Ruptured aneurysms arising from the origin of a DMCA can be successfully treated by embolization. These aneurysms are small and 3D-computed tomography reconstruction is mandatory to detect them. It is important to preserve the DMCA during the treatment procedure.

“…There is little relevance of the occurrence of the aneurysms in the DMCA, because of their rarity. 7) Kai et al 6) classified the DMCA into two types: type A and type B. According to Kai's classification, type A DMCA arises at the top of the ICA, giving the impression of an early bifurcation.…”

The duplicated middle cerebral artery (DMCA) is an anatomic variation that arises from the distal internal carotid artery (ICA) and supplies blood to the middle cerebral artery (MCA) territory. Aneurysms of the DMCA have been reported in 36 cases in 2020. We also report a case of a 3.7 mm saccular aneurysm originating from the DMCA. A 52-year-old woman visited our hospital with worsening headache. She had no neurological abnormalities. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) revealed a right distal ICA aneurysm at the anterior choroidal artery. Cerebral angiography was performed to confirm the shape and the size of the aneurysm. Cerebral angiography revealed that the vessel that was originally identified as the anterior choroidal artery by the MRA was actually the duplicated MCA that was originating from the aneurysm neck and was supplying the MCA territory. The patient's aneurysm was clipped using a transsylvian approach and she recovered without any neurological symptoms. DMCAs are rare and often associated with aneurysms and require preoperative evaluation to confirm the vascular status, aneurysm characteristics, and the shape of the parent artery.

“…Anatomical variation in the middle cerebral artery (MCA) are rare and classified into : duplicated MCA (DMCA), an accessory MCA, and fenestration of MCA 1,2,3,4 . The incidence of DMCA has been reported to be 0,7-2,9% on autopsy 4 , 0,81 % on magnetic resonance angiography (MRA) 3 and 0,24-1.5% on angiography 4,5 . We report a case of ruptured aneurysm at the origin of inferior part of duplicated middle cerebral artery.…”

Duplicated middle cerebral artery (DMCA) is an anomalous vessel arises from the internal carotid artery (ICA). This anatomical variation is rare. Aneurysm with this anatomical variation and unusual form was very rare. Even though this kind of aneurysm is rare, it was often ruptured. In this paper, we report a case of 40-years old female with abrupt decreased of consciousness as a chief complaint, along with severe headache one day earlier, no history of head trauma, and there was nuchal rigidity. She didn’t had history of hypertension before. Head computed tomography showed subarachnoid hemmorrhage (SAH) mostly on the left sylvian fissure with Hunt and Hess scale was 3 and Fisher scale was 2, while the cerebral angiography showed duplication of the left middle cerebral artery in which the inferior part of the MCA duplication has ruptured aneurysm at the origin. Treatment option for this aneurysm is endovascular coiling with preserved of the inferior part of duplicated MCA. Result of this treatment shows a good outcome.
