case_images: Computed tomography (CT) angiography of abdominopelvic imaging in retroperitoneal ganglioneuroma. (a) Giant retroperitoneal ganglioneuroma right sided under liver, slides between and encompassing the inferior vena cava (IVC) and aorta, it pushes forward the portal trunk and encases the celiac trunk, the aorta and the IVC more than 180 . (b) Retroperitoneal ganglioneuroma (RGN) encases the right renal artery at its origin and comes in contact with the right renal vein. (c) RGN gets in contact with the forward pancreas and splenic vein. Back, it is extended to anterior pararenal and perirenal space. It encases the superior mesenteric artery at its origin. (d) and (e) CT angiography of abdominopelvic imaging; an ovarian cystic mass pushes right to the uterus and measures 7 cm. HA: hepatic artery; PV: portal vein.

case_images: No intra- or retroperitoneal lymphadenopathy was observed (Figure 1).
case_images: (a) Perioperative view after total resection of Ganglioneuromas (GN) showed the release of all retroperitoneal vascular structure 1: inferior vena cava (IVC) 2: superior mesenteric artery (SMA) 3: celiac trunk (CeT) 4: Aorta 5: left renal vena (LRV). (b) Perioperative view after complete resection of RGN demonstrate the release of all retroperitoneal vascular structures. 1: IVC. 2: LRV. 3: SMA. 4: aorta. 5: stomach. (c) Image of the final surgical specimen of the GN.

case_images: In the pelvic space, a left ovarian cystic tumor was identified, hypodense with a thin wall, containing discreetly hyperdense sloping material, indicative of an ovarian dermoid cyst classified as O-rads 2 (on ultrasound; Figure 2).
case_images: Ganglioneuroma with admixture of ganglion cells and mature Schwann cells.

case_images: The final diagnosis was confirmed through histopathological examination of the specimens, revealing a synchronous retroperitoneal ganglioneuroma and a left ovarian endometrioma (Figure 3).
