  • Title: [Magnetic resonance imaging in craniopharyngiomas. The differential diagnosis of cystic intra- and suprasellar space-occupying lesions].
    Author: Baierl P, Fink U, Mayr B, Bauer WM, Oeckler R.
    Journal: Rofo; 1987 May; 146(5):578-83. PubMed ID: 3035647.
    Abstract:
    Seven patients with confirmed craniopharyngiomas were examined via magnetic resonance imaging. The various tumour components (whether solid, cystic or calcified) were evaluated separately. Three types of cysts were observed that can be distinguished by their signal intensity in various pulse sequences. This could be explained largely by an analysis of the T1 and T2 image contrast. The reason for the various types of cysts is determined by their cholesterol content. MR imaging is not as useful as CT for demonstrating the solid and calcified portions of the tumour and this reduces its value in diagnosing the type of tumour. Against that, it is superior with regard to separating the tumour from its neighbouring structures. The differential diagnosis, which must be considered in using MR, is summarised in a table at the end of the paper.
