M. Maffezzini et al., RENAL ANGIOMYOLIPOMA WITH EXTRARENAL INVOLVEMENT - IN VASCULAR, LYMPH-NODE AND PERIRENAL TISSUE, Scandinavian journal of urology and nephrology, 29(3), 1995, pp. 327-329
Extrarenal involvement was found in four cases of renal angiomyolipoma
. In one case the wall of the inferior right bronchial artery was infi
ltrated, lymph nodes were involved in two cases and the perirenal fat
in one case. Extrarenal extension does not seem to alter the prognosis
of renal angiomyolipoma. Expectant treatment of this rare condition t
herefore appears to be warranted.
