title: [Rare variation of abdominal aorta breaking in two].
abstract: OBJECTIVE
  To discuss a rare variation of abdominal aorta breaking in two.
  
  
  METHODS
  An in-patients, female, aged 76, admitted for asthenia of right extremities, underwent gadolinium-enhanced magnetic resonance angiography (MRA) of cerebral and abdominal vessels and abdominal MRI in whom the conventional angiography had failed to reveal this vascular abnormality.
  
  
  RESULTS
  MRA showed a clearly separated abdominal aorta. The upper part of the abdominal aorta terminated under the two renal artery branches and the lower part terminated at the level of L(3 - 4). The compensated enlarged superior and inferior mesenteric artery connected these two isolated parts of abdominal aorta.
  
  
  CONCLUSIONS
  This rare variation of abdominal aorta without any symptom is probably caused by some external force during the embryonic period.
