The radiologic diagnosis of pituitary adenoma: an overview.

The author reviews the literature on the radiologic diagnosis of pituitary adenoma, including the studies by Bruneton et al., Danziger et al., and Dubois et al. in this issue. Computed tomography is the definitive radiologic diagnostic tool in large pituitary adenomas (1.5 cm or greater). Precision radiographic studies, endocrine correlation, and an understanding of the effect of sellar variations on radiographic images can yield a very high incidence of accurate recognition of pituitary microadenomas. Computed tomography portends an even greater diagnostic sensitivity.
