ABSTRACT

Objective To compare the clinical and MRI characteristics of pituitary macroadenoma between male and female patients. Methods Two hundred and thirty patients with pathologically diagnosed pituitary macroadenomas (104 mlaes and 126 females) were divided into two groups according to different gender. Patient age, the ratio of intratumoral hemorrhage and cavernous sinus invasion, and tumor volume were calculated in each group and compared between the two groups. The constitution of different pathological types was also compared. Results The age, ratio of intratumoral hemorrhage and cavernous sinus invasion, and tumor volume was (44.8±13.2) years old, 21.15% (22/104), 50.00% (52/104), and 6100.48 (mm3, median) in the male group and (44.8±11.9) years old, 28.57% (36/126), 48.41% (61/126) and 5037.05 (mm3, median) in the female group, respectiveluy. There was no statistical difference between the two groups regarding to patient age, the ratio of intratumoral hemorrhage and cavernous sinus invasion, tumor volume, and constitution of pathological types (P=0.972, P=0.197, P=0.811, P=0.189, P=0.093, respectively). Conclusion Pituitary macroadenomas show no gender preference in clinical and MRI characteristics.
