Differential Diagnosis for Baby with One Testes Larger
- Single most likely diagnosis
- Hydrocele: A common condition in infants where fluid accumulates around a testicle, causing it to appear larger. This condition is often benign and resolves on its own.
- Other Likely diagnoses
- Hernia: An inguinal hernia can cause a testicle to appear larger due to the protrusion of intestinal tissue into the scrotum.
- Varicocele: An enlargement of the veins within the scrotum, which can cause a testicle to appear larger.
- Testicular torsion (early stages): Although more commonly associated with acute pain, early stages of testicular torsion might present with a larger testis before severe symptoms develop.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Testicular cancer: Although rare in infants, testicular cancer can present with a painless enlargement of a testicle. Early detection is crucial for effective treatment.
- Testicular torsion (advanced stages): This is a medical emergency that requires immediate attention. If missed, it can lead to the loss of the testicle and potentially long-term fertility issues.
- Rare diagnoses
- Epididymitis: Inflammation of the epididymis, which can cause swelling and enlargement of a testicle. This is less common in infants but can occur.
- Spermatocele: A cystic structure filled with sperm that can develop near the testicle, potentially causing it to appear larger.
- Polyorchidism: A rare congenital anomaly where an individual has more than two testicles, which could be mistaken for one testicle being larger.
