High-resolution computed tomographic appearance of the intrasellar contents in women of childbearing age.
Our experience with high-resolution computed tomography has indicated that the accepted norms for appearance and size of the pituitary gland may not be entirely valid for women of childbearing age. Fifty women with normal menstrual histories and who were not taking oral contraceptives were studied. The study consisted of overlapping 1.5-mm sections through the pituitary fossa in the coronal position only, using a bolus of contrast material followed by a continuous drip during the study. The results indicate that the top of the normal range of gland height is well over the accepted 7 mm and that focal defects within the gland are common. Other variables such as gland shape, width, and overall density were also evaluated.
