Prevalencia de adenomas hipofisiarios diagnosticados por resonancia magnética en el Instituto de Diagnóstico por Imagen, 2019 2020

Background: Pituitary adenomas are benign tumors that affect the CNS. They belong to 10- 15% of tumors in the sellar region (1). According to their size, they are divided either microadenomas or macroadenomas. Magnetic resonance imaging is really important for diagnosis: Gold standard method is the one used for assessment. Objective: To determine the prevalence of pituitary adenomas diagnosed by magnetic resonance imaging at the Institute of Diagnostic Imaging, 2019-2020. Methodology: Descriptive-retrospective study. 180patients who had pituitary adenomas were studied. This information was analyzed and tabulated usingIBM SPSS Statistics 25 according to set variables. Results: 247 radiological scans were examinated: 180 of then reported pituitary adenomas, showing a higher prevalence in females(76.7%), the most frequent time of appearance is between 31 and 40 years old. According to their size, microadenomas are the most common (69.4%). The most common radiological signs are regular borders (92.8%) and homogeneous intensity (68.9%). After contrast mediumadministration, a homogeneous uptake is visible (50%). Conclusions: Pituitary adenomas are more common in females and the most common age range is between 31 and 40 years. According to their size, microadenomas are the most frequent and the most common radiological signs are regular borders, homogeneous intensity and, in relation to contrast medium uptake, it was found that homogeneous uptake is more frequent.
