OBJECTIVE
A case of cholesterol granuloma of tunica vaginalis, with an equivocal ultrasound image but typical histopathological picture, is described.
PATIENT AND METHOD
A 33-year-old man complained of a painless scrotal mass of 17 years duration. The mass was 10 cm in diameter, could not be transilluminated and appeared as paratesticular and solid on ultrasound, suggesting a tumor. At operation an old hydrocele with cholesterol crystals and cholesterol granuloma of tunica vaginalis was found. A partial resection of tunica vaginalis was performed, sparing the testis.
COMMENT
Cholesterol granuloma is a rare inflammatory reaction of tunica vaginalis, that may simulate an intrascrotal tumor on physical examination, on ultrasound and at operation.
目的
描述一例睾丸鞘膜胆固醇肉芽肿病例，其超声图像不明确，但组织病理学表现典型。
患者及方法
一名33岁男性，主诉有一个持续17年的无痛性阴囊肿块。肿块直径10厘米，不透光，超声检查显示位于睾丸旁且为实性，提示肿瘤。手术中发现一个陈旧性鞘膜积液，伴有胆固醇结晶和睾丸鞘膜胆固醇肉芽肿。对睾丸鞘膜进行了部分切除，保留了睾丸。
评论
胆固醇肉芽肿是一种罕见的睾丸鞘膜炎症反应，在体格检查、超声检查及手术中可能类似阴囊内肿瘤。
