Abstract
We report a case of 48 year-old man with an infrarenal aortic tumor, presented with a contained rupture and osteolytic lesion of the third lumbar vertebra. The aortic tumor was resected en-bloc with graft interposition. Histological exam revealed poorly differentiated mesenchymal cells extending widely into the intima and also invading vigorously through the media destroying the wall structure. In spite of adjuvant chemo-radiotherapy, multiple lung metastasis appeared 1-year after the operation and the patient died due to rupture of the anastomotic pseudoaneurysm 35 months after operation. We report its clinical-course with the diagnostic imaging, applied therapy, and pathological findings of the resected specimen and autopsy.
