A 60-year-old man was admitted to our clinic because of perianal pain and diarrhea. Digital examination of the rectum revealed an extramural mass in the posterior wall of the rectum. Preoperative CT scan and endorectal ultrasonography demonstrated a multicystic tumor in the presacral space. The mass was diagnosed as a tailgut cyst. It was 4.0×1.8×1.3cm in size. The mass was removed using a parasacrococcygeal approach. The coccyx is removed and the sphincter is not divided. Histologically, the cyst membrane consisted of columar, squamous, and transitional epithelium, and the lesion was diagnosed as a tailgut cyst. Tailgut cyst is a rare entity, and only 19 cases have been reported in Japan. Both ultrasound and CT scan are beneficial in making a differential diagnosis. With spread of the term tailgut cyst, it may be more frequently diagnosed, among presacral cystic tumors.
