We present a 76-year-old patient with multiple renal angiomylipoma in one kidney.
The patient had not been having any urinary tract symptoms, the lesions in kidney
were visualized in US examination performed because of cholelithiasis suspicion.
Angiomyolipoma is included to the benign tumors of hamartoma group and its growth
is related to the hormonal activity of the organism. Multiple renal
angiomyolipomata, occurring very rarely, are usually related to the tuberous
sclerosis syndrome (Bourneville-Pringle disease). The nature of this disease is
the occurrence of multiple hamartoma type tumors in the skin, brain, kidneys,
heart, bones, lungs and eyes. Small renal angiomyolipomata are asymptomatic and
are usually accidentally diagnosed during imaging examinations, big ones may be
the reason of significant ailments. Among severe, life threatening complications
of renal angiomyolipoma one can number bleeding from the tumor. Bleeding risk
depends on the tumor diameter and significantly increases in tumors of the
diameter above 4 cm. Computed tomography is an imaging method recommended for the
assessment of hemorrhagic complications in angiomyolipoma. The check-up frequency
depends on the tumor diameter - in tumors smaller than 4 cm the examination is
performed once yearly, in tumors greater than 4 cm - every 6 months. In the
treatment of hemorrhagic complications of angiomyolipoma, a surgical treatment
(partial or radical nephrectomy) or renal vessel embolization is used. Renal
arteriography with embolization is an important therapeutic method to control the
bleeding and to avoid surgery.
