Which imaging study is essential to assess for intra-abdominal pathology in a child with a palpable varicocele?

• A. Abdominal/pelvic ultrasound
• B. Scrotal ultrasound
• C. CT abdomen
• D. MRI

Answer: (A)

When a child presents with a palpable varicocele, the possibility of an abdominal or retroperitoneal process causing venous congestion must be considered. The most informative initial test is an abdominal/pelvic ultrasound because it can visualize the kidneys, renal veins, and retroperitoneum to look for a mass, hydronephrosis, or venous obstruction that could explain the varicocele. It is noninvasive, radiation-free, and well suited for pediatrics. Scrotal ultrasound would confirm the presence of a varicocele and assess testicular health, but it doesn’t evaluate the abdominal structures that could be the underlying cause. CT or MRI can provide more detail if ultrasound findings are concerning or inconclusive, but they aren’t the first step due to cost, availability, and in the case of CT, radiation exposure.
