[Computer tomographic findings in tumours of the oesophagus (author's transl)].

The computer tomographic findings in 55 patients with histologically confirmed oesophageal carcinomas and in three benign oesophageal tumours are described. In 49 cases, the carcinoma was clearly visible on computer tomography, but in six cases, the tumour was not seen. In another six cases, infiltration into the mediastinum and trachea was demonstrated. In seven patients, regional lymph node metastases were found. The value of computer tomography in oesophageal carcinomas lies in the ability to demonstrate axial spread of the tumour, and the presence of lymphatic or haematogenous metastases during the one examination. This helps in the choice of surgery or in the planning of radiation treatment. Demonstration of the thickness of the oesophageal wall in the region of the tumour can be improved by using a flour-gastrografin paste.
