Retrorectal tumors.

ABSTRACT: Tumors that arise in the retrorectal (presacral) space are uncommon lesions that present with nonspecific signs and symptoms, which lead to difficult diagnoses. For complete evaluation of the lesion, cross-sectional imaging is required to determine the extent of resection and the appropriate surgical approach. Surgical removal leads to favorable outcomes for patients with benign purely cystic retrorectal tumors. Preoperative tissue diagnosis with transperineal and transsacral biopsies of solid or heterogeneous cystic lesions, are essential to determine the necessity of neoadjuvant therapy, which may decrease local recurrence after surgery and avoid an unnecessary delay in systemic therapy.
