The most undesired complication of renal angi-
omyolipoma (AML) is bleeding. Because of tumor rupture,
the bleeding can spread to the retroperitoneal field and
can be severe enough to be life threatening. We report a
case of retroperitoneal hemorrhage caused by a ruptured
AML that was successfully treated with transarterial
embolization with N-butyl cyanoacrylate.
