The patient was a 64-year-old man who had a family history that his daughter had surgical treatment of tailgut cyst. A pelvic CT scan which was done for the purpose of screening of PSA elevation revealed a presacral tumor. The size of this cystic tumor was 34mm with solid part and was located in S2-5 levels. Laparoscopic transabdominal and transsacral approach surgery was performed. Postoperative course was uneventful. This tumor was diagnosed as a tailgut cyst by pathological findings and involved no malignancy. Tailgut cyst has malignant potential in 2-13%. The treatment of a presacral tumor should be complete surgical removal. The combined approach of transabdominal and transsacral approach with laparoscopy was useful because it provided good overview in pelvic, which is important for complete resection and preserving pelvic nerval structures.
