Abstract

When a swelling arising in the gluteal region herniates into the pelvic cavity through the sciatic foramen, it is referred to as inverse or reverse sciatic hernia and is a rare occurrence. We present the case of a 62-year-old female who presented with swelling in the left gluteal region with features of sciatica and abdominal pain. Magnetic resonance imaging showed 27 cm × 22 cm × 9cm soft tissue swelling arising from the gluteal region and inversely herniating into the pelvic cavity through the sciatic foramen. We were successful in delivering the tumor through a gluteal approach. Lipomatous tumors presenting as inverse sciatic hernia are a rare event.
