- W4387394325 abstract "Rationale and Objectives. Twig-like middle cerebral artery (MCA) is a rare anomaly where the M1 MCA is partially or completely replaced by a plexiform network. It has been described in angiographic series from Asian and South-American cohorts, but has not yet been reported in a European population. Materials and Methods. The digital subtraction angiograms (DSA) of adult patients referred to a single neurovascular center for a diagnostic hypothesis of Moyamoya arteriopathy (MMA) from 2018 to 2023, were prospectively and retrospectively checked by experienced neuroradiologists for identifying patients with twig-like MCA. The angioarchitecture of twig-like MCA was systematically evaluated and described. Results. 5/30 (16.7%) male patients (mean age 55.8 + 14.7 years) of European ancestry were identified as twig-like MCA. The clinical presentations were ischemic stroke (2/5), hemorrhagic stroke (1/5), and headache (2/5). All patients showed a unilateral involvement on DSA and in 1/5 (20%) an intracranial aneurysm was found. DSA was used to confirm the diagnosis of twig-like MCA and define the angioarchitecture and associated anomalies. An accessory MCA and recurrent artery of Heubner (RAH) were found in 3/5 (60%) cases, feeding the network together with the anterior choroidal artery (4/5, 80%). Conclusions. Twig-like MCA is a rare vascular anomaly, but it seems to be less rare than expected among adult European patients with suspected MMA on noninvasive neuroimaging studies. DSA is fundamental for a reliable differential diagnosis and should not be omitted in these patients." @default.
