A retrospective case series was conducted using contrast-enhanced computed tomography scans of the chest performed at National Hospital Sri Lanka. A total of 50 CT studies were reviewed. Bovine aortic arch was identified based on established imaging criteria. Demographic characteristics and associated vascular variations were recorded. Descriptive statistics were used to calculate prevalence and percentages. Comparison between male and female patients was performed using Fisher’s exact test, and statistical significance was set at p < 0.05. Bovine aortic arch was identified in 14 of 50 patients, yielding a prevalence of 28%. The median age of the individuals was 64 years (range 0.44–81 years). Nine cases occurred in males and 5 in females, with no statistically significant difference between genders (p = 0.77). One patient demonstrated an associated left vertebral artery arising directly from the aortic arch. No additional major arch anomalies were included in this focused series. The presence of a Bovine aortic arch is a common aortic arch variant in this Sri Lankan cohort, with a prevalence comparable to previous local data and at the higher end of global estimates. Recognition of this variant on CT imaging is important due to its potential implications for vascular and endovascular procedures.
