Herniation pit is a round, radiolucent lesion with a well-defined margin in the cortical bone on the antero-lateral side of the femoral neck. An asymptomatic lesion, it is incidentally found on simple radiography. Sometimes this lesion is the cause of hip pain, but surgical procedure is very rarly needed. Here we are presenting a case report of a 24-year-old male who presented with symptomatic herniation pit and needed surgery. As shown in the current case, there were no cases for which a curettage has been performed through the expansion of the orifice of herniation pit using arthroscopy. At a 11-month follow-up, the patient had no recurrent episodes.
