Le diagnostic radiologique des tumeurs malignes du pharynx et du larynx.

This is virtually an atlas, beautifully illustrating the detail of anatomic structure of the neck as seen in roentgenograms. Those showing the altered contours and densities of the larynx and pharynx are supplemented in many instances by drawings, which point out the details. The topography of normal anatomic structures is outlined against abundant evidence of proved pathologic changes. There are descriptions of special roentgen technic designed to bring out the detail of soft tissue for the study of the mechanism of phonation as well as altered contours which result from infections or from benign or malignant neoplasms. The author places considerable emphasis on the character of the margins of a mass. Diffuse densities are more likely to be the result of malignant invasion, as compared with the homogeneously dense, sharp demarcated outline of a benign growth. Granulomatous changes of tuberculosis and syphilis may resemble neoplastic infiltrations. Dr. Baclesse has had
