It is characterized by predilection for embryonal tumor growth, especially Wilms tumor (WT), and manifestations like lateralized overgrowth/hemihypertrophy, macroglossia, macrosomia, anterior abdominal wall defects, and hyperinsulinism. Our case is a 1 year of female child who presented with abdominal swelling and limb length discrepancies. A clinical diagnosis of BWS was made based on multifocal WT and hepatomegaly and nephromegaly detected on contrast-enhanced abdominal computed tomography and physical examination findings of lateralized overgrowth and umbilical hernia. A molecular genetic test was not available. The patient was started on preoperative chemotherapy with good tolerance. Clinical criteria can be used to diagnose WBS in a setting where confirmatory molecular testing is unavailable. This will considerably change approaches to management of presenting complications such as WT .
