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

Abstract

BackgroundWe 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 presentationThis 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.ConclusionsThe 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.

Surgical management of retroperitoneal cystic Schwannoma complicated by retrograde ejaculation - Case report

“…The most commonly observed complication is recurrence (5–10%) [6] . Only two other studies [7] , [8] , other than ours, indicated postoperative autonomic nerve system dysfunction due to Nervi Erigentes' manipulation. The Nervi Erigentes are splanchnic nerves that arise from sacral spinal nerves that migrate through the hypogastric plexus along the cavernous nerves, providing parasympathetic innervation to erectile bodies [9] .…”

“…1 It usually occurs in the cephalocervical region and limbs but is rare in the presacral region. 2,3 Schwannoma is a benign tumor that can cause intense FDG uptake. 4 The quinoline-based imaging agent tracer FAPI can be used to detect a variety of cancers.…”
