 A 50-year-old woman was referred to the Department of Internal Medicine of Hyogo Prefectural Nishinomiya Hospital in January 201X for close monitering of hypertension. Abdominal contrast computer tomography revealed a retroperitoneal mass, measuring 8cm in diameter, with an enhanced component. She was thus referred to our department for consultation to determine whether surgery was indicated. Although retroperitoneal hematoma was suspected preoperatively, non-functional retroperitoneal tumor with denatured bleeding could not be completely ruled out. It was found that this tumor was compressing the inferior vena cava from the ventral side. Therefore, laparoscopic retroperitoneal tumor resection was performed. Even though the patient's body mass index was 30.54kg/cm2, we were able to perform laparoscopic resection safely. The tumor was carefully dissected through retroperitoneal approach via the mesenteric pedicle. Good visualization was possible with the use of pneumoperitoneum. Histologically, the tumor was a retroperitoneal hematoma with encapsulated fibrosis and was not malignant. Laparoscopic surgery allowed expansion as well as horizontal direction of the visual field, making it possible to resect this giant tumor.
