Report interpretation
This ultrasound is reassuring about the testes themselves:
- Both testes are normal in appearance and blood flow.
- No testicular torsion, tumor, infection, varicocele, or significant fluid around both testes is reported.
- The important finding is on the right side:
- A fluid collection, about 3.3 × 1.9 × 2.3 cm, is present in the right scrotum.
- It appears to communicate with the abdomen through the right inguinal canal.
- This is called a right communicating hydrocele due to a patent processus vaginalis (PPV).
What this means
A communicating hydrocele occurs when a small passage between the abdomen and scrotum has not closed. Fluid can move through it, so the right scrotal swelling may become bigger when the child is standing, crying, coughing, straining, or later in the day, and smaller when lying down.
At age
5 years, this is less likely to close on its own. A communicating hydrocele can sometimes allow bowel or other abdominal tissue to enter the canal, causing an
inguinal hernia. The scan does
not say that bowel is currently in the scrotum, but the open passage means the risk exists. A pediatric reference explains that persistence of this passage causes childhood hydroceles and inguinal hernias (Campbell-Walsh Urology, p. 1138). The
American Academy of Pediatrics guidance similarly notes that communicating hydroceles may change in size and that surgery is needed if an inguinal hernia develops.
Solution / next step
Please arrange an appointment with a pediatric surgeon or pediatric urologist soon, ideally within the next few days to weeks, carrying this report.
The usual definitive treatment at this age is a planned minor operation called:
- Right inguinal herniotomy / ligation of patent processus vaginalis, often referred to as hydrocele or hernia repair.
The surgeon closes the open connection between abdomen and scrotum. Medicines, massage, creams, or home remedies cannot close this passage.
Go to emergency immediately if any of these occur
- Sudden severe groin or scrotal pain
- Swelling becomes hard, red, very tender, or cannot be reduced
- Persistent crying due to pain
- Vomiting, abdominal bloating, refusal to eat
- Fever with painful swelling
- The child appears unusually unwell
These can suggest a trapped inguinal hernia and need urgent assessment.
Until the surgical consultation, normal gentle activity is generally fine if the child is comfortable, but avoid pressing, squeezing, or trying to force the swelling back.
