A 76-year-old female patient diagnosed as having a retroperitoneal tumor was referred to our hospital for surgery. Preoperative imaging examinations revealed the diagnosis of leiomyosarcoma arising from the IVC. We performed partial resection of the IVC and reconstruction using a PTPE patch without nephrectomy, because the tumor was not found to invade the renal vein or artery. Histopathology revealed leiomyosarcoma of the IVC with SMA and Caldesmon-positive cells. At present, 5 months since the surgery, the patient has shown no evidence of recurrence. This case serves to underscore the need to consider the appropriate surgical method preoperatively in cases of leiomyosarcoma of the IVC, in order to preserve the kidneys.
