Aberrant adrenal tissue is rare, particularly in adults. To the best of our knowledge, only eight cases have been reported in the English literature. Awareness of the possible occurrence of adrenal tissue in hernial sac is crucial, as these rests may have several clinical implications. These potential implications include hyperplasia, adrenal insufficiency, neoplastic transformation and misdiagnosis as metastatic clear cell carcinoma. We report a rare case of aberrant adrenocortical tissue in hernial sac. We review the literature and highlight the clinical implications of this incidental finding.
