[The significance of mammographic symptoms in clinically occult findings].

The significance of various radiographic signs in 183 patients with clinically occult breast disease is described. 30.6% had a carcinoma of the breast or a carcinoma in situ. The radiological features have varying predictive values and there is variation in the incidence of lymph node metastases. It is considered useful to classify the radiological appearances under the headings of round foci, star-shaped opacities, diffuse opacities, opacities with calcification and groups of micro-calcification. Despite the early diagnosis, 24% of patients already had lymph node metastases.
