Abstract

Objective: To investigate the size and shape of the pituitary gland in Vietnamese individuals in relation to sex and age. Subjects and Methods: A total of 360 participants underwent brain magnetic resonance imaging using 3D T1-weighted sequences. Pituitary gland dimensions were measured, and morphological characteristics were assessed. Results – Conclusion: The average pituitary gland measurements were as follows: height 5.69 ± 1.40 mm; anteroposterior diameter 11.05 ± 1.32 mm; transverse diameter 13.08 ± 1.98 mm; anterior lobe anteroposterior diameter 8.05 ± 1.30 mm; posterior lobe long axis 5.26 ± 1.13 mm; short axis 3.24 ± 0.90 mm; and transverse diameter 8.09 ± 1.64 mm. The most common gland shape was concave (45.00%), followed by flat (32.78%), convex (12.78%), partially empty sella (7.50%), and completely empty sella (1.94%). Significant differences between males and females were observed in pituitary height, anteroposterior and transverse diameters, and anterior lobe anteroposterior diameter. No significant sex differences were found in posterior lobe parameters or gland shape. Age showed a significant negative correlation with pituitary height and transverse diameter, and a significant positive correlation with the short axis of the posterior lobe. Other measurements did not significantly correlate with age.
