Presacral tumors are uncommon lesions that can be difficult to diagnose because of their nonspecific presenting signs and symptoms. Surgery is the mainstay of treatment as it establishes the diagnosis and prevents the adverse consequences associated with malignant degeneration and secondary bacterial infection. Large, highly vascularised pelvic tumors may pose intraoperative difficulties as bleeding and intraoperative tumor perforation. Cross-sectional imaging is essential in evaluating these lesions to determine the optimal surgical approach and the extent of resection. We emphasize a multidisciplinary expert individualized approach. We report a case of a presacral giant gastrointestinal tumor initially considered as unresectable but further on successfully managed by preoperative vascular embolization followed by resection via abdomino-perineal approach.
