CT of pituitary microadenomas.
In reading the well documented article by Davis et al. [1] in the November/December 1984 issue of AJNR, we found the title of the article to be perhaps a bit provoking and the authors' conclusion rather severe for high-resolution computed tomography (CT) of pituitary microadenomas. Two points should be emphasized: 1. The authors are correct in stating that "gland height greater than 8 mm and an...
متن کاملTomographic abnormalities simulating pituitary microadenomas.
False-positive and false-negative interpretations of sellar tomography were found in about one-fifth of cases in a recent autopsy study correlating the presence of pituitary microadenomas with abnormal sellar tomograms. An analysis of minor variations in the bony configuration of the sella disclosed variations due to posterior lobe asymmetry, intercavernous venous channels, bony asymmetry, and ...
متن کاملMR of corticotropin-secreting pituitary microadenomas.
PURPOSE To assess the accuracy of MR in the preoperative identification of corticotropin-secreting pituitary microadenomas. METHODS Twenty-six patients with clinical and biochemical evidence of pituitary-driven Cushing disease in whom MR of the seller region was performed were selected for this study. The MR examinations were retrospectively evaluated by a neuroradiologist who was aware of th...
متن کاملProlactin-secreting pituitary microadenomas: inaccuracy of high-resolution CT imaging.
Computed tomographic (CT) and surgical findings were correlated retrospectively in 51 patients with preoperative diagnoses of prolactin-secreting pituitary microadenomas. Thirty-nine had microadenomas at surgery. Twenty-three had identifiable discrete lesions. Of these, 21 had microadenomas and two did not; these two groups could not be distinguished reliably. Six patients with proven microaden...
متن کاملCushing's disease: a comparison of pituitary corticotroph microadenomas and macroadenomas.
Cushing's disease appears as a functionally heterogeneous disease, but criteria that are able to distinguish between different clinical forms remain elusive. We compared two subgroups of patients with proven Cushing's disease according to the size of the pituitary adenoma, evaluated by computed tomography or magnetic resonance imaging. Our series comprised 11 patients with a microadenoma and 10...
