Twig-like or unfused middle cerebral artery (MCA) is a rare congenital vascular anomaly defined by the absence of the M1 segment. It can be found incidentally or can be revealed by cerebral ischemia or hemorrhag

Two patients presented with nonaneurysmal SAH due to an unfused or twiglike MCA. Both patients had stenosis of the proximal M1 segment of the left MCA and abnormal vascular nets distal to the stenotic lesion. Vasculature distal to the abnormal vascular nets remained grossly normal. These findings...

Introduction: Twig-like middle cerebral artery (T-MCA) or rete mirabile anomaly is a rare vascular anomaly with clinical relevance characterized by the replacement of the M1 segment by a plexiform network of small vessels1. With an incidence ranging from 0.11% to 1.17%, it is more prevalent ...
Twig-like MCA is an extremely rare entity, believed to result from the persistence of the fetal intracranial arterial network that normally merges into a definitive MCA. This vascular lesion is frequently misdiagnosed, and seems to be related to a higher incidence of aneurysms and susceptibility ...
T-MCA = twiglike MCACongenital anomalies of the MCA are rare compared with the rest of the intracranial vasculature. An aplastic MCA, known as a twiglike MCA, is the result of replacement of MCA trunk by a plexiform network of small vessels. In this report, we aim to review the ...
Anomalies of the middle cerebral artery (MCA) are very rare. ?Rete MCA,? ?twig-like MCA? (T-MCA), ?aplastic MCA,? ?unfused MCA,? and others are all synonyms for unilateral embryological anomaly of the M1 segment of the MCA, where, due to an unknown cause, fusion of primordial ...
