Large presacral abscess in a patient with Crohn’s disease

Abstract

Abstract A presacral abscess with sacral osteomyelitis and gluteal abscesses is a very rare complication of Crohn’s disease and is often clinically unsuspected or overlooked. We report a case of a 58-year-old male who presented for right hip pain after a fall. An abdominal and pelvic CT scan showed an atypical presacral abscess with a fistulizing tract extending through the sciatic notch and lateral to the gluteus medius and minimus muscles forming an intramuscular abscess. The endoscopic transanal approach was used to drain the presacral abscess. This method of drainage was successful and the patient had a favorable prognosis.
