Abstract

A review was made of the computed tomographic (CT) studies of 33 patients with hormone-secreting microadenomas that had been verified by transsphenoidal surgery and endocrinologic evaluation. In previous studies in small series of patients, the CT appearance of pituitary microadenomas has been reported as hypodense, isodense, and hyperdense. In this study, CT showed a region of diminished enhancement and usually an enlarged pituitary gland in cases of prolactin-secreting adenomas. HGH- or ACTH-secreting adenomas were less consistently hypodense. It is concluded that hypodensity and enlargement in the pituitary gland are the most useful criteria for identification of microadenomas. Some technical factors that may affect the CT appearance of microadenomas and lead to conflicting reports are discussed.

摘要

对33例经蝶窦手术及内分泌评估证实的分泌激素微腺瘤患者的计算机断层扫描（CT）研究进行了回顾。在先前对少数患者的系列研究中，垂体微腺瘤的CT表现曾被报道为低密度、等密度和高密度。在本研究中，CT显示泌乳素分泌腺瘤病例中存在强化减弱区域，且垂体通常增大。生长激素或促肾上腺皮质激素分泌腺瘤的低密度表现则不太一致。得出的结论是，垂体低密度及增大是识别微腺瘤最有用的标准。还讨论了一些可能影响微腺瘤CT表现并导致相互矛盾报告的技术因素。
