Infant with a right inguinal mass

US of inguinal hernia
Sagittal US of the scrotum (below) shows a loop of bowel superior to the right testicle within the right scrotal sac. Transverse US (above) best demonstrates the presence of a reactive hydrocele around the loop of bowel. The bowel was subsequently successfully reduced into the abdomen and repaired 3 days later.

The diagnosis was right inguinal hernia.
