title: [A Case of Retroperitoneal Liposarcoma].
abstract: A 52-year-old man visited a local hospital complaining of abdominal distension. Enhanced computed tomography scan revealed a giant retroperitoneal tumor surrounding the left internal iliac artery and left kidney. We performed en bloc tumor resection with left internal iliac artery resection. The tumor was 35 cm in size and weighed 6,860 g. The histological diagnosis was a dedifferentiated liposarcoma. After surgery, the patient experienced left lower limb paralysis. Clinical examination and neurological findings suggested a lumbosacral problem. After 6 months, the patient's lower limb paralysis had not improved. It is important to note that ischemic neuropathy may be related to internal iliac artery resection.
