Differential Diagnosis for Enlarged Testicle
Single Most Likely Diagnosis
- Hydrocele: a common condition where fluid accumulates in the scrotum, causing the testicle to appear enlarged. This is often due to inflammation or injury.
Other Likely Diagnoses
- Varicocele: an enlargement of the veins within the scrotum, similar to varicose veins, which can cause the testicle to appear larger.
- Epididymitis: inflammation of the epididymis, a tube at the back of the testicle that stores and carries sperm, often due to infection.
- Orchitis: inflammation of one or both testicles, usually caused by bacterial or viral infections.
Do Not Miss Diagnoses
- Testicular Torsion: a medical emergency where the spermatic cord becomes twisted, cutting off the blood supply to the testicle. Prompt diagnosis and treatment are crucial to save the testicle.
- Testicular Cancer: although less common, testicular cancer can cause an enlarged testicle. Early detection is key for effective treatment.
Rare Diagnoses
- Spermatocele: a rare, benign cystic accumulation of sperm that can occur near the testicle, causing it to appear enlarged.
- Hematocele: a collection of blood in the scrotum, which can be due to trauma or a bleeding disorder, leading to an enlarged appearance of the testicle.
- Filariasis: in endemic areas, this parasitic infection can cause severe swelling of the scrotum and testicles, known as hydrocele or elephantiasis.
