Cause of postprandial vomiting - a giant retroperitoneal ganglioneuroma enclosing large blood vessels: A case report

Figure 1 Multiphase enhanced computerized tomographic images of the patient. A: Giant retroperitoneal hypodense mass in pre-contrast and punctate calcification could be noted; B: The hypodense mass without enhancement in arterial and venous phase, and the stomach and kidneys were compressed and displaced; C: The mass presented mild enhancement in venous phase; D: The mass showed patchy and flocculent enhancement in delay phase, and the extent of enhancement was greater than that of the venous phase.

Figure 2 The computerized tomographic images of tumors surrounding blood vessels. A-D: Tumor-enclosed arteries: hepatic artery (A), splenic artery (A, B), bilateral renal artery (C), superior mesenteric artery (D); E, F: Tumor-enclosed veins: Portal vein (E) and inferior vena cava (F).
