Abstract
Schwannomas are a type of benign nerve sheath tumor originating from Schwann cells that very rarely originate from nerves within the pelvis. Here, we report a case of a 65-year-old male with a background of rectal adenocarcinoma who had a lesion identified within his right lateral pelvic wall on an MRI scan, initially believed to be metastatic spread to a lymph node. He underwent a laparoscopic abdominoperineal resection as well as a lateral pelvic side wall dissection. Histopathology identified the lesion as a schwannoma, which, upon review of the recorded laparoscopic footage, was identified as originating from the obturator nerve.
