Anomalies of anterior cerebral artery (ACA) include aplasia, hypoplasia and variations in number. Magneticresonance angiography (MRA) is a non-invasive diagnostic technique for assessment of anomalies of cerebral arteries. Theaim of the study was to determine the role of MRA in detection of variants of ACA in adults. This study is an observationalretrospective study. This study included forty-nine adult cases (28 males and 21 females), mean age 48±12.9 SD withanomalies of ACA in MRA. Magnetic resonance imaging of the brain and MRA were done to all patients. Cerebral MRA andmagnetic resonance images were evaluated for frequency and distribution of variants of anterior cerebral arteries, associatedaneurysms and infarctions. Odds ratios (ORs) and relative risk were calculated to determine risk of occurrence of cerebralinfarctions in patients with anomalies of ACA. Hypoplasia of ACA was the commonest anomaly of ACA (51% of cases). Riskof occurrence of cerebral infarctions was higher in cases with azygos variant (OR, 3.3; P=0.35) than in those with hypoplasticACA (OR, 2; P=0.58). MRA was highly reliable in identification of different variants of ACA and concomitant vascularchanges.
