Purpose/Background: To present a 30-year multicenter experience in the multidisciplinary management of presacral tumors, emphasizing the role of MRI-based surgical planning, approach selection, and clinical outcomes to support evidence-based decision-making in complex pelvic surgery.

Methods/Interventions: A multicenter retrospective case series was conducted including patients diagnosed and surgically treated for presacral tumors between January 1989 and December 2024. Demographic, clinical, radiologic, histopathologic, and surgical variables were analyzed descriptively. Quantitative data were summarized as mean ± standard deviation or median (interquartile range), and qualitative variables as absolute and relative frequencies.

Results/Outcomes: Sixteen patients were included, with a mean age of 49 ± 10.6 years; 63.2% were female. Median symptom duration was 8 months (IQR 5-18), with pain being the most frequent presentation (64.2%). The mean tumor size was 95.8 ± 38.7 mm, predominantly retrorectal (87.5%). The Kraske posterior approach was used in 75% of cases. Histopathology showed epidermoid or dermoid cysts in 31.6%, followed by schwannomas and teratomas (15.8% each). Complete resection was achieved in 87.5% of patients. No procedure-related morbidity or mortality occurred within 30 days.

Conclusion/Discussion: Presacral tumors are rare and diagnostically challenging entities that require a high index of suspicion. MRI provides essential anatomic detail for accurate assessment and surgical planning. Optimal outcomes depend on multidisciplinary management and complete resection in specialized centers.
