[Roentgenological characteristic of pulmonary metastases in thyroid cancer in respect of its biological behaviour (author's transl)].

In metastases of the lung which must be considered as typical in cancer of the thyroid, it is possible to differentiate roentgenologically between fine and coarse nodules, the limit being approximately 10 mm. Metastases consisting of fine nodules are by no means to be considered as representing a fatal generalisation, whereas metastases with coarse nodules are frequently accompanied by other metastases distant from the primary tumour.
