Differential Diagnosis for Nonpainful Testicular Swelling
Single Most Likely Diagnosis
- Hydrocele: A collection of fluid around a testicle, often causing nonpainful swelling. It is a common condition, and its diagnosis is often made based on physical examination and ultrasound findings.
Other Likely Diagnoses
- Varicocele: Enlargement of the veins in the scrotum, which can cause nonpainful swelling. It is often diagnosed based on physical examination and Doppler ultrasound.
- Epididymal cyst: A benign cystic structure attached to the epididymus, which can cause nonpainful swelling. Diagnosis is often made by ultrasound.
- Spermatocele: A benign cystic structure filled with sperm, which can cause nonpainful swelling. Diagnosis is often made by ultrasound.
- Testicular cyst: A benign fluid-filled structure within the testicle, which can cause nonpainful swelling. Diagnosis is often made by ultrasound.
Do Not Miss Diagnoses
- Testicular cancer: Although less common, testicular cancer can present with nonpainful swelling. It is crucial to perform a thorough physical examination, obtain a complete medical history, and consider imaging studies and tumor markers to rule out this diagnosis.
- Testicular lymphoma: A rare type of cancer that can cause nonpainful swelling. It is essential to consider this diagnosis in older adults or those with a history of lymphoma.
Rare Diagnoses
- Polyorchidism: A rare congenital anomaly where an individual has more than two testicles, which can cause nonpainful swelling.
- Testicular torsion with a long-standing history: Although testicular torsion typically presents with acute pain, a long-standing history of torsion can lead to nonpainful swelling due to chronic ischemmia.
- Granulomatous orcharm: A rare inflammatory condition that can cause nonpainful swelling, often associated with systemic diseases such as sarcoidosis or tuberculosis.
