Retroperitoneal ganglioneuroma: A five-case series from a single Tunisian center

Abstract

Introduction and importanceRetroperitoneal ganglioneuroma is an infrequent, benign tumor originating from the sympathetic nervous system. The diagnosis predominantly relies on histological assessment, often as an incidental discovery. Surgical removal stands as the primary treatment modality, and the overall prognosis tends to be favorable. Case presentationObjective: In order to comprehensively examine the diagnostic, therapeutic, and progressive aspects of retroperitoneal ganglioneuroma, this study aims to analyze five cases of retroperitoneal ganglioneuroma that were surgically managed between 1993 and 2013.Patients and methods: We present a series of five cases involving retroperitoneal ganglioneuromas that underwent surgical intervention in the urology department of Charles Nicolle Teaching Hospital of Tunis between the years 1993 and 2013. The study cohort comprised three females and two males, with an average age of 36.4 years (ranging from 10 to 88 years). Among these cases, four instances showcased incidental tumor detection, while one case manifested with cruralgia due to nerve compression. Complete tumor excision was achieved in all cases, with a single instance necessitating concurrent nephrectomy. Accurate diagnosis was ascertained through meticulous histological examination. Clinical discussionResults: The case series encompassed three women and two men, with an average age of 36.4 years (ranging from 10 to 88 years). The majority of cases (four out of five) unveiled tumors incidentally, whereas one case presented with cruralgia. Surgical removal resulted in complete resection of all tumors, although nephrectomy was necessary in one instance. Postoperative complications were minimal, and effective anticoagulant treatment addressed one thrombotic event. While recurrence was noted in a solitary case, subsequent imaging confirmed its stability. The average follow-up duration extended to 23.2 months (ranging from 6 to 72 months). ConclusionRetroperitoneal ganglioneuroma, being a rare and benign neoplasm, mandates meticulous pathological assessment and precise imaging for precise localization. Unquestionably, complete surgical resection remains paramount to forestall recurrence and mitigate the likelihood of malignant transformation. Overall, the prognosis associated with retroperitoneal ganglioneuroma tends to be favorable.
