Classification of tumours in the sellar region using CT and encephalotomography

Tumours in the sellar region may still present diagnostic problems. We therefore compared encephalotomographic and CT findings in sellar tumours and 91 patients were examined by both methods. For clinical purposes and operative treatment the degree of compression of the hypothalamus is of great importance. Encephalotomographic and CT findings are analysed and demonstrated. In cases of density differences between tumour and brain tissue shown by contrast enhancement, more information on the inner structure of a tumour (cystic or solid) can be obtained by computerized tomography. But if these are no density differences or/and contrast enhancement, tumour diagnosis is made easier by encephalotomography because of the great efficiency of this method.
