Differential Diagnosis for Enlarged Testicle
- The following categories outline potential causes for an enlarged testicle:
Single Most Likely Diagnosis
- Epididitis: This is the most likely diagnosis due to its high prevalence and association with testicular pain and swelling, often caused by bacterial or viral infections.
Other Likely Diagnoses
- Orchitis: Inflammation of the testicle, often caused by bacterial or viral infections, which can lead to swelling and pain.
- Hydrocele: Accumulation of fluid around the testicle, causing swelling, which can be primary (idiopathic) or secondary (due to trauma, infection, or tumor).
- Varicocele: Enlargement of the veins in the scrotum, which can cause swelling and discomfort.
Do Not Miss Diagnoses
- Testicular Torsion: A medical emergency where the testicle twists, cutting off blood supply, requiring immediate attention to prevent damage or loss of the testicle.
- Testicular Cancer: Although less common, it is crucial to rule out testicular cancer, as it can present with a painless testicular mass or swelling.
Rare Diagnoses
- Spermatocele: A cystic structure filled with sperm, which can cause swelling but is usually painless.
- Hematocele: Accumulation of blood in the scrotum, often due to trauma, which can cause swelling and pain.
- Filariasis: A parasitic infection that can cause swelling and inflammation of the scrotum, more common in tropical regions.
