[Ultrasound in the diagnosis of cystic lesions of the liver (author's transl)].

Possibilities and limitations of the use of ultrasound in diagnozing cystic liver diseases are discussed with reference to our own investigations. Solitary or multiocular liver cysts can be detected in the right proportion and in the correct anatomical position from about 1.5 cm in size; they are often coincidental findings after ultrasonography. The ultrasonic method is a simple investigation technique without any complications or contraindication and it now has a firm place as a screening investigation programme within diagnostic procedures especially before an intended liver needle biopsy or puncture during laparoscopy. By carrying out ultrasonic investigations on families of patients with cysts of the liver it has been possible to make an early diagnosis of hereditary cystic disease.
