Abstract
A 62-year-old man consulted a previous doctor because of anemia which had been pointed out at a blood donation, and an abdominal computed tomography (CT) scan showed a huge retroperitoneal mass. He was referred to our hospital for further examination. Enhanced CT scan revealed a large retroperitoneal tumor, which was surrounding the aorta and deviated the IVC to ventral and the right kidney, which presented hydronephrosis to the lateral cranial side.
The patient underwent a surgical operation on a diagnosis of retroperitoneal malignant tumor. The huge mass, 17×14×9 cm in size, was resected en bloc with the right kidney, right psoas muscle, part of the aorta and the inferior vena cava. Vascular reconstruction was performed using an aorta-iliac Y-graft and an IVC-right iliac vein I-graft.
The pathological examination of the specimen revealed dedifferentiated retroperitoneal liposarcoma invading the aorta and IVC.
