PSA is usually an incidental finding and is exceedingly rare to find bilaterally.Case Report: We present the case of a rare presentation of PSA that resulted in a favorable outcome for a patient who sustained a gunshot wound to his midthigh and discuss the history, embryology, anatomy, classification schema, imaging evaluation, complications, diagnosis, and management of PSA.Conclusion: PSAs are of doubtful clinical significance when found incidentally at imaging; however, individual patient symptoms, unique arterial anatomy, and the PSA classification best determine the appropriate treatment options.
