Twig-like middle cerebral artery
Updates to Study Attributes
NECT of the brain shows a zone of post-ischemic -ischaemic encephalomalacia in the left striatocapsular region with widening of the left lateral ventricle. No signs of intracranial bleeding or new ischemicischaemic changes.
A small hyperdense subcortical lesion in the right frontal lobe with no perifocal edemaoedema, probably consistent with a vascular lesion.
Polypoid changes of the paranasal sinuses.

Updates to Case Attributes
This case demonstrates the absence of the main trunk of the right MCA. It is not a result of arterial occlusive disease because of the absence of any ischaemic or post-ischaemic changes in right MCA territory which must inevitably occur in case of occlusion of so big cerebral artery. So, it is a developmental anomaly known as twig-like MCA.
Incidental variant anatomy of right PCA - fetal origin and and DVA of the right frontal lobe.
