摘要

Variations of the anterior cerebral artery and anterior communicating artery complex are common. However, an infraoptic course ofA1 segment of Anterior Cerebral Artery (ACA) is a rare anatomic variation, detection of which is critical due to its association withformation of aneurysms in the anterior circulation. The diagnosis is purely radiological and MRI, Magnetic Resonance Angiography(MRA), and Computed Tomography angiography (CT angiography) have emerged as the modalities of choice because of their abilityto depict the intracranial vessels accurately. Both CT and MR angiography are preferred over catheter angiography because oftheir non-invasive nature. Time of ?ight MR angiography is an MR angiography technique which demonstrates intracranial vesselswithout administering gadolinium based MR contrast medium and is therefore safe for all age groups and all patient categories.Here, authors present the MR fndings that lead to the radiological diagnosis of anomalous infraoptic anterior cerebral artery in apatient presenting with an episode of transient ischaemic attack.
