Congenital 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 radiologic features of a twiglike MCA and its differential diagnosis, helping the reader differentiate this entity from more common pathologies to avoid unnecessary further investigation.
