Core Tip

Core Tip: Accurate diagnosis of hepatic echinococcosis is crucial, especially for high-mortality hepatic alveolar echinococcosis. Ultrasonography is recommended as the first-line examination for hepatic echinococcosis in endemic areas. This review focuses on the clinical features and ultrasonographic diagnosis of this disease, emphasizing the importance of early detection in endemic regions to improve clinical outcomes. Additionally, this review presents classic images of conventional ultrasound, contrast-enhanced ultrasound, and intraoperative ultrasound to illustrate different stages and types of hepatic cystic and alveolar echinococcosis, thereby facilitating their differentiation from other focal liver lesions.
