ABSTRACT
INTRODUCTION: Ganglioneuromas are rare benign neoplasms arising from the sympathetic neuroendocrine system. These tumors usually occur in the abdomen and tend to grow around major blood vessels making often their complete excision challenging and demanding. PRESENTATION OF CASE: The authors present the challenging surgical management of a sizable retroperitoneal extra-adrenal ganglioneuroma involving the infrahepatic inferior vena cava, portal triad, celiac axis and superior mesenteric artery in a 23-year-old female patient. The tumor was safely and completely excised in toto with preservation of all neighboring vital anatomical structures using a midi laparotomy access. DISCUSSION: Ganglioneuromas should be included in the differential diagnosis of any retroperitoneal mass. Their management involves total surgical excision however, in some instances; it can be challenging and demanding because of their tendency to engage neighboring vital anatomical structures. CONCLUSION: A surgical strategy including meticulous operative dissection guided by the quality principles of surgical oncology although challenging and demanding can result to a safe and complete tumor excision, which is directly correlated with an improved patients' postoperative outcome and excellent prognosis.
