Which cyst is commonly described as rare and can be single or multiple, sometimes containing septations or hemorrhage?

• A. Tunica Albuginea Cyst
• B. Epididymal Cyst
• C. Tunica Vaginalis
• D. Spermatic Cord Cyst

Answer: (C)

Cysts within the tunica vaginalis are uncommon scrotal lesions that can be either solitary or multiple and may show septations or hemorrhagic changes. On ultrasound, they appear as well-defined, discrete cystic spaces located outside the testicular parenchyma but within the tunica vaginalis. The cysts typically have thin walls and show posterior acoustic enhancement; if complex, they may contain internal septations or echo debris from hemorrhage. Doppler usually shows no internal blood flow, helping distinguish them from vascular solid masses. These cysts are distinct from an epididymal cyst, which lies in the epididymis rather than within the tunica vaginalis; from a tunica albuginea cyst, which arises within the tunica albuginea on the testicular surface; and from a spermatic cord cyst, which tracks along the spermatic cord rather than near the testis itself.
