Esophageal carcinoma : radiologic appearance of minimal lesions

Twelve minimal lesions were found over a period of 18 months at the Istituto Nazionale Tumori of Milan at the end of the radiologic, endoscopic and histologic procedures. Eleven lesions were radiologically detected, and a radiologic diagnosis of malignancy was perspectively made in 10 of the identified lesions. The radiologic aspects of minimal lesions are described. Double contrast study of the esophagus allows excellent mucosal detail and good reproduction of lesions. Simplicity and minimal discomfort for the patient justify it as a first diagnostic step for detection of neoplastic pathology.
