“…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.

RESUMO ABSTRACTWe present the case of a female patient, 35 years old, who had a complaint of sporadic left flank pain for 5 years. She said she had no comorbidities. The results of the laboratory tests did not show abnormalities. Previous ultrasonography of the urinary tract (without the use of color Doppler) described a possible single cyst postero-inferiorly to the left renal pelvis. In recent ultrasound we observed that topography massive oval formation markedly hypoechoic with discrete intermingled flow. Subsequent abdominal computed tomography and magnetic resonance imaging characterized retroperitoneal mass along the hilum of the left kidney, associated with renal dimensional reduction and ipsilateral hydronephrosis.Histological diagnosis after tumor excision: cell schwannoma (Antoni A histological standard only).
