[Angiographic features of liver echinococcosis (author's transl)].

From 1973 to 1978 13 cases of cystic hydatid disease and 15 cases of alveolar hydatid disease of the liver were diagnosed by angiography. The main diagnostic features of cystic hydatid disease of the liver are the following: "rim-sign", avascular areas, curved displacement of the arteries and stretching of the intrahepatic arteries. Multilocular hydatid disease of the liver shows tumor-like angiographic signs, such as atypical vascular formations, distensions, vascular irregularities, arterial stenoses as well as hepatosplenomegaly. Differential diagnosis in malignant liver diseases is often impossible, but early venous filling and arteriovenous shunts are not characteristic of multilocular hydatid disease of the liver. Particularly difficult is the interpretation in patients who have had previous surgery.
