Answer- B. Nephroblastoma(Wilms tumor)
Wilms tumor originates from renal embryonic tissue and is the most common renal tumor in children aged 1-5 years.
– It commonly presents as an abdominal mass detected on imaging.
– The tumor expands within the kidney, pushing the normal parenchyma aside and laterally displacing it on ultrasound.
– Other features may include hematuria, hypertension, and sometimes abdominal pain.
– Neuroblastoma:
– Arises from adrenal medulla or sympathetic chain
– Displaces kidney inferiorly and medially
– Common in infancy to early childhood
– Often shows calcifications and encases vessels
– Renal Cell Carcinoma (RCC):
– Rare in children, mostly affects adults
– Usually presents with hematuria and flank pain in adults
– Not a typical cause of abdominal mass in infants
