Abstract

Wilm's tumor (nephroblastoma) is the most common pediatric renal malignancy, typically occurring in children under 5 years of age, with peak incidence between 3–5 years. We report a rare case of an 8-month-old infant who presented with complaints of swelling over the left lumbar region for 1 week, which was gradually increasing and associated with reduced urine output and multiple episodes of vomiting. Imaging with ultrasonography (USG) abdomen and contrast-enhanced computed tomography (CECT) confirmed the diagnosis. The patient was managed using a multidisciplinary approach following the SIOP protocol, including preoperative chemotherapy, followed by nephrectomy and postoperative chemotherapy. The postoperative period was uneventful, and the patient is currently under follow-up with stable clinical condition. This case highlights the importance of early diagnosis in atypical age groups and emphasizes that Wilm's tumor, although uncommon in infants, should be considered in the differential diagnosis of abdominal masses. Early intervention with a structured multidisciplinary approach can significantly improve prognosis.
