Wilms' Tumor in Horseshoe Kidney

Abstract

Wilms' tumor is the most common malignant kidney tumor found in children. The Horseshoe kidney is the most common renal fusion malformation. However, Wilms' tumor is rarely identified in horseshoe kidney patients. Multimodal treatments in Wilms' tumor can play important roles in increasing the survival rate. In this study, we report the case of a 6-year-old boy in whom a Wilms' tumor was identified in a horseshoe kidney. The tumor was successfully treated with preoperative chemotherapy, followed by surgical resection.

Keywords: Children; Horseshoe kidney; Renal tumor; Wilms' tumor.

Abdominal CT images revealed the presence of a large mass located in the isthmus of the horseshoe kidney, which primarily developed toward the left side of the abdomen (a, arrow). This mass showed heterogeneous enhancement, with less enhancement relative to the normal kidney parenchyma (a, arrowhead). Abdominal CT image after 12 weeks of chemotherapy treatment revealed a significant reduction in tumor size (b, arrowhead). CT, computed tomography.
