title: [Cysts and cystoid formations of the neck: significance and possibilities of radiodiagnosis].
abstract: The differential diagnosis of lateral cysts of the neck, metastatically altered lymph nodes and malignant tumors sometimes is difficult because their X-ray images as well as their clinical manifestations can be alike. The data of examination of 55 patients were analyzed. They included 43 cases of cysts of the neck (26 lateral and 17 median), 10 cases of cystically altered metastases into the lymph nodes, 2 cases of malignant tumors. The examination included US investigation (USI), computed tomography (CT), USI controlled aspiration biopsy. The diagnosis was histologically verified in 46 patients, in 7 cases the material was investigated cytologically. The "atypical" echographic picture was noted in 30.9% of cases with lateral cysts and in 23.6% of cases with median cysts. They had irregular shape, defective contours, echostructure of the tissues with repeated complications in anamnesis, weak "dorsal reinforcement". The clinical investigation of cases with lateral cysts was exact in 76.9%, with median cysts--in 82.4%. The USI examination was exact in 96.2% of cases with lateral cysts and in 94.1% with median cysts. CT was exact in 94.4% of cases with lateral cysts, and in 100% with median cysts. Thus, USI is thought to be necessary as the first step of X ray examination when cyst of the neck was suspected. Large sizes, spread of the cyst into deep areas and into the larynx lumen are considered as indications to CT. Both the echographic and computed tomography picture of the neck cysts depend on their localization, character of the content and the presence of inflammatory symptoms. The USI controlled aspiration biopsy can make the "atypical" USI picture of the mass nature more exact.
