Abstract

This article describes the ultrasound features of kidney angiomiolipomas in children. Kidney angiomyolipomas, being benign neoplasms, can be detected both in isolation and as part of a genetically determined pathology, such as tuberous sclerosis. Sometimes angiomyolipomas can be isoechoic and not be visualized by ultrasound, which is due to the small amount of fatty tissue in the tumor. With tuberous sclerosis, not only angiomyolipomas can be detected in the kidneys, but also cystic changes. Sometimes cysts are the only renal manifestation of tuberous sclerosis, making diagnosis difficult. Currently, the diagnosis of tuberous sclerosis is based on a set of clinical diagnostic criteria. Complications of rapidly growing angiomiolipomas can include bleeding, chronic kidney disease up to the terminal stage. The article describes cases of visualization of isolated angiomiolipomas and cases of visualization of angiomiolipomas in tuberous sclerosis, describes the differences between them. Renal manifestations of tuberous sclerosis are not yet widely represented, so dynamic ultrasound monitoring can play a significant role in accumulating knowledge on this issue, assessing the effect of targeted therapy on angiomiolipomas growth inhibition and the incidence of complications.
