Here, we report an unusual case of spontaneous rupture of AAA into a renal cyst that presented with hematuria, abdominal pain and shock, and which was diagnosed with multidetector computed tomography. We also review the literature on unusual patterns of AAA rupture. [J Chin Med Assoc 2009;72(10):551–554] © 2009 by Lippincott Williams & Wilkins, Inc.
