Which finding is associated with epididymal inflammation or trauma and shows multiple tiny cysts in the mediastinum testis with no color flow?

• A. Extratesticular
• B. Tubular Ectasia of the Rete Testis
• C. Intratesticular Cyst
• D. Cystic Dysplasia

Answer: (B)

Tubular ectasia of the rete testis is the dilation of the tubules in the mediastinum of the testis. It commonly occurs after epididymal inflammation or scrotal trauma. On ultrasound it presents as multiple tiny anechoic cystic structures clustered in the mediastinal region of the testis, with no internal color Doppler flow. The pattern is characteristic because the dilation is confined to the rete testis area and the surrounding testicular parenchyma remains normal, and the lack of vascularity helps distinguish these from solid or malignant intratesticular lesions. Extratesticular pathology would lie outside the testis, not in the mediastinal region. Intratesticular cysts are within the testicular parenchyma rather than the mediastinum. Cystic dysplasia typically appears as multiple cysts within the testis, often in younger patients, and isn’t specifically tied to epididymal inflammation or trauma in the mediastinal region.
