[Diagnostic imaging in the evaluation of non-neoplastic space occupying pathology in the sellar and suprasellar region].

Before the introduction of computed imaging techniques like CT scan and MR, the differential diagnosis of lesions affecting the sellar and suprasellar regions was very difficult, more often impossible. These techniques contributed to ameliorate the typing of pathological tissues. Non neoplastic pathological findings of this region are very different and they can variate between phlogistic processes, vascular lesions, hamartomatous formations or congenital malformations. In this work we describe the characteristic changes of morphology and radiologic aspect in the diagnostic study of this region, using CT scan and MR imaging.
