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.
