Hypertension accompanying a Wilms tumor occurs in about 10–27% of children, but cardiomyopathy associated with a Wilms tumor is very rarely described. This publication presents a case of a 9-month-old girl with a bilateral Wilms tumor accompanied by dilated cardiomyopathy since her initial cancer diagnosis, as well as her off-protocol treatment. The severe condition of the child forced the application of off-protocol treatment, i.e., accelerated resection of a larger tumor, which enabled the improvement of heart performance and made subsequent therapy possible. In the course of the presented treatment, a gradual normalization of cardiac ventricular function and contractility was observed. In conclusion, a massive abdominal tumor associated with abdominal compartment syndrome compromised the functioning of the cardiovascular system in the young child. Therefore, earlier removal of Wilms tumors in patients with heart failure should be considered. This may result in the improvement of cardiovascular function and the possibility of further therapy. Keywords: cardiomyopathy; children; cardiotoxicity; hypertension; Wilms tumor 1. Introduction Wilms tumors (nephroblastoma) are the most common kidney cancer in children [1]. More often, the tumor occurs in children with hemihypertrophy or children with another malformation of the genitourinary, cardiovascular, or musculoskeletal system [1]. Usually, the disease affects one kidney, but in 5–10% of cases, it is bilateral [2,3]. Wilms tumors are genetically heterogeneous and mutations in WT1, WTX, and CTNNB1 underlie the genetic basis of about one-third of Wilms tumors. Another gene mutation found in Wilms tumors is the AMER1 gene. Changes on the short arm of chromosome 11 where IGF2 and H19 genes are located were also associated with development of a Wilms tumor.
