Laparoscopically excised retroperitoneal presacral Schwannoma: atypical pre and postoperative manifestations - case report

Bárbara Justo Carvalho et al. BMC Surg. .

Abstract

Background: We are a reporting a rare case of retroperitoneal schwanomma with atypical pre and postoperative manifestations. Retroperitoneal schwannomas are rare tumors that are difficult to preoperatively diagnose.

Case presentation: This is a case report of a male patient, 41 years old, with symptoms of hipogastric and lower right member pain, as well as a history of a papilliferous thyroid tumor. Computerized tomography exams were inconclusive, showing a mass in the presacral region with dimensions of 4.4 × 3.9 × 3.4 cm. Removal was carried out by laparoscopic surgery, with self-limited postoperative complications. Diagnosis was carried out by anatomopathological examination, and syndromic hypotheses were discarded.

Conclusions: The postoperative complications of schwanomma are little reported in the literature. In the simultaneous occurrence of schwanomma and other endocrine tumors, further studies are warranted to better differentiate the cases that need investigation of syndromic causes.

Keywords: Laparoscopy; Multiple endocrine Neoplasia; Neurilemomma; Papillary carcinoma; Postoperative complications.
