[Complex radiation diagnosis of the intrathoracic thyroid]

The study deals with a complex radiation diagnosis of mass lesions of the distopic thyroid. Forty five patients with mass lesions of the anterior mediastenum were examined. They were 28 with retrosternal and intrathoracic goiter, 6 with teratodermoid tumors, 11 with cysts of the anterior mediastenum. A complex radiation study included serial routine X-ray tomography in 2 standard projects, sonography, computed tomography. The diagnosis was verified on the basis of transthoracic and transbronchial needle biopsy with compulsory morphological confirmation. An intergroup comparison has shown that X-ray study is a screening method to detect a tumor, to define its site and its relationship with the adjacent organs. Ultrasound study reveals pathognomonic signs of the distopic goiter. Of the greatest informative value is X-ray CT which allows one to state about the structure of a tumor and its densitometric signs.
