Hypopituitarism due to pituitary lesions may have unclear clinical manifestations, and for its diagnosis it is necessary to conduct a hormonal examination. There are clinical recommendations to conduct a hormonal investigation in all cases of pituitary tumors > 6 mm that seems to be uncertain.The objective to evaluate the frequency of hypopituitarism in patients with pituitary macroadenomas with different hormonal activity and to identify its possibl...

There are clinical recommendations to conduct a hormonal investigation in all cases of pituitary tumors > 6 mm in size that seems to be uncertain.The objective: To reveal features of pituitary macroadenomas with at least one size less than 10 mmThe materials and methods: We have analyzed medical records of 380 newly diagnosed patients with pituitary macroadenomas before any treatment: 162 non-functioning adenomas (NFAs), 74 pro...

Introduction: Previous studies demonstrated a relationship between T1- and T2-weighted signal intensity and tumor growth pattern in pituitary somatotropinomas. The goal of this retrospective study was to analyze the MRI characteristics of pituitary macroadenomas with different hormonal activity in newly diagnosed patients.Material and methods: Pre-treatment T1- and T2-weighted MR-images (Intera Achieva, PHILIPS, 3.0T) of patients with 42 non-functional a...
