Ultrasound appearance of congenital renal disease: Pictorial review

Congenital renal diseases consist of a variety of entities. The age of presentation and clinical examination narrow down the differential diagnosis; however, imaging is essential for accurate diagnosis and pretreatment planning. Ultrasound is often used for initial evaluation. Computed tomography (CT) and MRI provide additional information. Ultrasonography continues to occupy a central role in the evaluation and detection of congenital renal diseases due to its advantage of rapid scanning time, lack of radiation exposure, cost effective and easy feasibility.
