Ultrasound diagnosis of liver hydatid disease.
A clinical study of 42 patients with hydatid disease was carried out using a real-time gray scale B-scanner. All cases were confirmed surgically. The ultrasound characteristics of the hydatid cysts were classified into three groups: Type I, simple hydatid cyst (19 of the 42 cases), type II, hydatid cyst with a disrupted wall and septa (14 cases), and type III, hydatid cyst with a heterogeneous echo pattern (9 cases). It was concluded that ultrasound classification of the cysts increases diagnostic accuracy. However, if a hydatid cyst becomes secondarily infected these typical changes are lost and the ultrasound diagnosis may then become more difficult. Periodic examinations should be performed with ultrasound after surgery.
