2022

Introducción. En el espacio retrorrectal o presacro pueden desarrollarse lesiones tumorales, tanto benignas como malignas. La mayoría de los pacientes son asintomáticos y, cuando presentan síntomas, éstos son inespecíficos. Entre los tumores retrorrectales se destaca el grupo de origen neurogénico, donde el Schwannoma es el más frecuente. Caso clínico. Mujer de 32 años, con tumor retrorrectal, que producía una sintomatología escasa e imprecisa, diagnosticado durante una intervención quirúrgica por mioma uterino, que finalmente resultó ser un Schawnnoma. Conclusión. La tomografía computarizada y la resonancia magnética son importantes para el diagnóstico y para establecer el nivel de la lesión en relación con el sacro. La piedra angular del tratamiento es la resección quirúrgica. El abordaje puede ser anterior (abdominal), posterior (perineal, transsacro o parasacrococígeo) o combinado, de acuerdo con su localización al nivel S4.

“…In a review of 82 retroperitoneal schwannomas, only 15.9% of tumors were identified preoperatively using these imaging techniques. 10,11 Late discovery of presacral tumors is common because of their slow-growing nature and nonspecific symptoms. Thus, at the time of diagnosis, these tumors tend to be considerably large.…”

Laparoscopic Resection of Retroperitoneal Presacral Schwannoma: A Case Report

et al. 2018

Retroperitoneal presacral schwannomas are uncommon and are usually diagnosed accidentally. We present here the case of a 23-year-old woman diagnosed with an expansive pelvic lesion during a routine gynecological examination. The precise location of the tumor, as well as its relation to adjacent structures, was determined through magnetic resonance imaging (MRI). The patient underwent laparoscopic lesion resection and the diagnosis was confirmed by immunohistochemistry. An MRI performed 2 months after surgery confirmed complete lesion resection.

“…Not a few authors argued that the treatment of choice for tumors is complete surgical excision 1 , 3 , 10 , 12 , 19) . Nevertheless, giant presacral schwannoma has a risk for surgical approach because of its huge size and proximity to abundant vascularity of presacral region 7 , 10) . In literatures, the approach to the tumor was described in various directions 3 , 16 , 17 , 19) .…”

Single Stage Posterior Approach for Total Resection of Presacral Giant Schwannoma: A Technical Case Report

et al. 2017

The neurogenic tumor of frequent occurrence in the presacral area is a schwannoma. Giant presacral schwannoma has a risk for anterior surgical approach because of its massive size and proximity to abundant vascularity of presacral region. We report a single stage posterior approach for total resection of a giant presacral schwannoma. A 40-year-old female patient experienced left buttock pain and tingling sensation at left S1 dermatome. Magnetic resonance imaging showed that the presacral huge mass at S1–3 level with osseous extension and structural remodeling in left sacral ala. The presacral mass was ranging in maximum diameter from 8.0 to 8.6 cm. S2 foramen laminectomy was performed to expose the mass. The tumor capsule and the root were carefully dissected away. The tumor was removed while preserving the capsule by dissecting the plane between the inner wall of the capsule and the tumor. The single stage posterior approach for presacral giant schwannoma is feasible, and it can be a good surgical alternative to prevent pelvic organ or vascular damage and anterior approach related dystocia and infertility.
