[Diagnosis and treatment of echinococcosis in an unusual location]

Data on 52 cases of hydatid disease of a rare localization are discussed. The patients were divided into two groups: first--hydatid disease of the viscera (42) and second--hydatid disease of the subcutaneous fat and the muscles (10). The diagnosis of hydatid disease of the viscera of rare localization was established by a complex of methods (radiological, scanning, laboratory tests, and serological studies). Laparoscopy and pneumoperitoneumography helped in making the precise preoperative diagnosis. Diagnostic puncture of the formed mass is important in the diagnosis of hydatid disease of the skeletal muscles and subcutaneous fat. The method of choice, basically, is closed echinococcectomy with complete or partial excision of the fibrous capsule with removal of the residual cavity depending on the localization of the cyst.
