Routine dissection of the gluteal region of a female cadaver revealed bilateral tendinous foramina that encircled portions of the right and left superior gluteal artery, nerve, and vein. These unique structures have not been previously described within the gluteus medius muscles. Clinicians should be mindful of this rare anatomical variation while performing surgical procedures in the gluteal region due to the increased risk of damaging the superior gluteal neurovascular bundle.
