Contribution of computerized tomography to the diagnosis and postoperative study of sellar tumors

The computerized tomography (C.T.) of 18 patients with sellar tumours were analysed. The C.T. made before surgery in 6 cases was positive in 3 and the type of tumour suggested by C.T. was confirmed in 3. Twelve patients had a C.T. investigation after surgery and the examination suggest recurrent tumour in 5. Two of these were re-operated. One patients with cholesteatoma had the recurrent tumour verified by surgery and the other, with a pituitary adenoma during re-operation was noted only cicatricial tissue at sellar region.
