ABSTRACT

Background: image diagnosis methods have changed the way we approach the different pathologies which affect the sellar region; magnetic resonance and computed tomography are the methods of choice for evaluation.
Objetive: identify differential diagnoses of lesions of the sellar region, which resemble macroadenoma, and their different characteristics, by image studies.
Material and Method: a retrospective and descriptive studio; we examined 117 patients with diagnosis of lesion of the sellar region in the period from March 2011 to March 2016 in a magnetic resonance service, and analyzed the different characteristics by image studies and their correlation with histopathological diagnoses.
Results: female patients were most commonly affected by lesions of the sellar region, at a rate of around 64%; concordance between radiological and histopathological diagnoses was found in 61.2% of cases; the most common diagnoses to consider in our population are: craniopharyngioma, meningioma, chordoma, and germinoma, taking into consideration rarer differential diagnoses such as tuberculoma, histiocytosis, macroadenoma with lymphocytic hypophysitis, and cystic lesions.
Conclusion: knowing the different differential diagnoses, and characteristics by image studies, of lesions of the sellar region will help improve diagnosis, treatment, and prognosis and reduce potential complications. Magnetic resonance is the procedure of choice to evaluate localized lesions in that region.
