Alveolar hydatid disease of the liver: brief review and spectrum of adjacent organ invasion.

Abstract: The purpose of this study is to show the spectrum of adjacent organ invasion and to make a brief review of hepatic alveolar hydatid disease (AHD), using CT and MR imaging. We retrospectively reviewed CT and MR images of three patients with various adjacent organ invasions surgically and histologically proven to be AHD. Local invasion to right kidney and adrenal, right hemidiaphragm and lung were detected in one patient, right adrenal in another patient and gall bladder, duodenum, gastric wall and pancreas invasion in the other. AHD may rarely extend to the gall bladder, stomach, duodenum, pancreas, right adrenal and kidney, diaphragm, pleura and lung. The extension of the disease outside the liver is usually encountered in patients with large, peripherally located masses in the advanced stage of the disease.

[Serum antibodies in cystic and alveolar hydatid disease (author's transl)].

Abstract: Serum samples of 107 patients with cystic and 30 with alveolar hydatid disease were tested for antibodies with hydatid fluid and extract from cyst material of E. alveolaris as antigens. Complement-fixation, indirect haemagglutination and an indirect enzyme immune (ELISA) technique were employed. The results indicate an antibody picture which confirms the value of serum-antibodies in the diagnosis of hydatid disease. Diagnostically insufficient antibody formation was present in seven patients with cystic and two with alveolar hydatid disease. The indirect haemagglutination test with alveolaris antigen proved to be the most sensitive reaction for antibody demonstration of both echinococci, while the same antigen in the ELISA technique gave species-specific results in patients with E. alveolaris.

Alveolar hydatid disease of the spine causing paraplegia.

Abstract: Hydatid disease involving the vertebral body and paravertebral soft tissues is a rare disease with poor prognosis. We report a case of spinal cord compression caused by secondary extradural cysts.

A case of liver cystis wlud Em18-WB was useful for differential diagnosis

Abstract: A 72-year-old woman with multilocular liver cysts was admitted. This lesions seemed to be an alveolar hydatid disease. Two methods of Western blotting were used for serologic diagnosis. One method recognizes antigens of crude extracts of Echinococcus multilocularis (EM). The other method recognizes a purified antigen (Em18) of EM. Her serum only reacted with the former method and never reacted with Em18 antigen. Eighteen months after first admission, she had an operation. The resected specimen was diagnosed with simple cysts. Western blotting using Em18 antigen could greatly facilitate the differential diagnosis of simple liver cyst and alveolar hydatid disease.
