The authors performed xerosialography on 41 patients with various diseases of the salivary glands. In 38 patients this provided positive information. Each of eight submandibular sialograms was abnormal; of the 33 parotid examinations, three benign salivary tumours could not be demonstrated radiologically. Xeroradiography is a useful method for the examination of the major salivary glands. It is superior to the traditional film method.

Pneumocystography established the preoperative diagnosis of 20 intracystic breast tumours including 9 benign intracystic papillomas and 11 cases of intracystic carcinoma generally considered to be a rarity. The method is described and details about the clinical and radiologic appearances of both benign and malignant intracystic tumours are given. The importance and advantages of the method are emphasized.
