[Postoperative radiological control in space occupying lesions of the sellar region (author's transl)].
Different methods of postoperative radiological examination of space occupying lesions of the sellar region are discussed with regard to early diagnosis of recurrences. The important role of regular controls by lateral radiographs of the skull is stressed in this follow up survey of 164 cases over a period of 23 years. Comparisons of radiographs over a period showed in 80% of our cases whether there was a tumour recurrence or not. Radiological changes in the area of the sella can be demonstrated more clearly by the use of magnified lateral radiographs and a centimetre rule. With regard to frequency and time of recurrence, 40% of first recurrences were found after 5 years, so periodic radiographic follow up X-ray examinations should be carried out six monthly intially, and later at twelve month intervals. Examples are demonstrated. Intraoperative marking of the diaphragm and dorsum sellae with gold foil for later control radiography is evaluated. Today, space occupying lesions, including intrasellar pituitary tumours, can be clearly demonstrated with the CT scan after i.v. injection of contrast medium to intensity the shadow of the tumour tissue.
