Abstract
A 44-year-old male who had been involved in a traffic accident was transferred to our hospital with pale face and low back pain. On admission, anemia and renal dysfunction were evident in the laboratory test. CT scan showed subcapsular hematoma of the left kidney and retroperitoneal hemorrhage. Following enhanced CT scan for embolization therapy revealed DeBakey type III b aortic dissection. Conservative treatment kept a subcapsular hemoatoma and aortic dissection stable during the hospital stay. The patient was discharged on the 42nd hospital day, while retaining mild renal dysfunction. Six months after discharge, the subcapsular hematoma increased again, and the left kidney was extracted. He had no trauma on his body and no past history of renal, autoimmunological and hematological disease, neither a family nor a drug-related history. We didn't suspect that his aortic dissection had caused this renal subcapsular hematoma because of its chronic process, and the kidney pathological findings failed to reveal the cause of the subcapsular renal hematoma.
