Laparoscopic Resection of Retroperitoneal Presacral Schwannoma: A Case Report

Abstract

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.

Resumo

Schwannomas pré-sacrais retroperitoneais são incomuns e geralmente diagnosticados acidentalmente. O caso apresentado envolve uma mulher de 23 anos, que teve o diagnóstico de lesão expansiva pélvica estabelecido em consulta ginecológica de rotina. A ressonância magnética ajudou a determinar a localização precisa do tumor e suas relações com estruturas adjacentes. A paciente foi submetida à ressecção da lesão por técnica laparoscópica e o diagnóstico de Schwannoma foi confirmado histopatologicamente e por imunohistoquímica. O exame de ressonância magnética realizado dois meses após a cirurgia confirmou a ressecção completa do tumor.
