The second case is a year-old female with the diagnosis of nephroblastoma after percutaneous biopsy of a right renal mass.

Nuclear medicine studies are utilised in the diagnostic pathway to detect occult disease and assess for nefrolbastoma bony spread.

They can be simplified as major vascular encasement, airway compression or CNS infiltration. Moreover, in our country, the incidence of advanced and metastatic Wilms’ tumor is considerably higher than in the western literature as the patients usually present in the late stages with large tumors and many a times with metastates.
