Abstract

The "snowflake sign" in liver brucellosis refers to a characteristic appearance on radiological imaging. It is caused by a calcified granuloma within the liver, resulting from a chronic Brucella infection. This calcification often has a distinctive "snowflake" pattern due to its radiating, irregular shape. This sign can be a valuable clue in diagnosing hepatic brucellosis, especially in regions where the disease is endemic.

摘要

肝布鲁氏菌病中的“雪花征”指的是放射影像学上的一种特征性表现。它由肝脏内的钙化肉芽肿引起，是慢性布鲁氏菌感染的结果。由于这种钙化呈放射状、不规则形状，常常具有独特的“雪花”样形态。该征象在诊断肝布鲁氏菌病时可能是一个有价值的线索，尤其是在该病的地方性流行区域。
