摘      要：Retrorectal or presacral tumors are rare lesions located in the presacral area and considered as being derived from multiple embryological *** tumors are classified as congenital,neurogenic,osseous,inflammatory,or *** most common among these are congenital benign lesions that present with non-specific symptoms,such as lower back pain and change in bowel *** congenital and developmental tumors occur in younger patients,the median age of presentation is reported to be 45 *** resonance imaging plays a crucial role in treatment management through accurate diagnosis of the lesion,the evaluation of invasion to adjacent structures,and the decision of appropriate surgical *** usefulness of preoperative biopsy is still debated;currently,it is only indicated for solid or heterogeneous tumors if it will alter the treatment *** resection with clear margins is considered the optimal treatment;described approaches are transabdominal,perineal,combined abdominoperineal,and minimally *** retrorectal tumors have favorable long-term outcomes with a low incidence of recurrence,whereas malignant tumors have a potential for distant organ metastasis in addition to local recurrence.
