title: LOWER BACK PAIN--SILENT SYMPTOM OF CHRONIC INFRARENAL ABDOMINAL ANEURYSM RUPTURE.
abstract: BACKGROUND
  The rupture of infrarenal abdominal aortic aneurysm is a surgical emergency condition with a high rate of mortality before the patients arrive at hospital. The signs and symptoms of abdominal aortic aneurysm rupture into the retroperitoneal cavity are pulsatile mass, abdominal pain, hypotension and shock, but sometimes silent symptoms also hide a dangerous and life threatening condition, such as chronic aneurysm rupture of abdominal aorta into the retroperitoneal cavity.
  
  
  METHODS
  We present a patient having had the lower back pain for 4 months, which had been recognized and treated as lumbar ischialgia but which was eventually diagnosed to be chronic infrarenal abdominal aortic aneurysm rupture by computed tomography angiography. The surgical intervention was successful and the patient was discharged from hospital after 6 days without any clinical complications. Preoperative imaging by computed tomography angiography of ruptured abdominal aortic aneurysm is highly sensitive for detection of several specific signs for rupture. This condition leads to urgent vascular surgery.
