Background: Right sided aortic arch is slightly rare variant of aortic arch which requires more description and elaboration for the management in clinician point view. This may remain asymptomatic or present with various vague symptomatology. It is mandatory for the clinician to be aware of the underlying anatomical details which may sometimes be responsible for the presenting complaints. Furthermore, this anomaly may also be associated with other abnormalities. Case presentation: We present 60-years old male who complained of headache and vague chest pain of two weeks duration and underwent Contrast Enhanced Computerized Tomography (CECT) chest for further evaluation. There was an incidental finding of right sided aortic arch with Aberrant Left Subclavian Artery (ALSA). This anomaly was not responsible for any of the symptoms as per the CECT findings. Conclusion: It is important to know the detailed relationship of right sided aortic arch with ALSA to the other neighboring anatomical structures. MDCT and MRI are always helpful tools to appreciate and apprise the clinician about the details of the anomaly in view of the management if required. Sometimes the symptoms may be present because of the compression by the vascular rings.
