Hydrocele stone: a rare case report.

Hydrocele, characterized by fluid accumulation in the tunica vaginalis, is a common benign scrotal condition. While unusual, hydrocele can lead to rare complications such as infection or lithiasis. A 60-year-old man presented with a 2-month history of left-sided scrotal swelling and discomfort. Physical examination and ultrasound revealed a large, nontransilluminant swelling with hyperechoic images. A provisional diagnosis of scrotal hydrocele with secondary lithiasis was made, and surgical exploration was performed. Intraoperatively, a fluid collection with small, hard stones was found. Cholesterol crystals were identified in the stone. Scrotal lithiasis in hydrocele is rare and is believed to result from stagnant fluid creating an ideal environment for cholesterol crystal formation. Ultrasound is crucial for diagnosis, revealing hyperechoic stones within the fluid collection. Surgical exploration, aspiration of fluid, and stone removal are standard treatments, usually conducted through a small scrotal incision, with a high success rate. [ABSTRACT FROM AUTHOR]
