鞍区病变的CT诊断

CT Diagnosis of Lesions of Sellar Region

我科自1980年5月至1983年1月对56例各类鞍区病变进行了CT检查,并据此作出诊断进行了治疗。现就各类病变的CT表现进行分析,总结其特点,以利于鉴别诊断。并对如何提高诊断的准确性进行讨论。

CT scans of 56 canes of sellar lesions are reviewed. Among them pituitary adenomas and craniopharyngiomas were commonly seen, and the others were glioma, meningioma, chordoma, pituitary abscess and empty sella. The CT scans of pituitary adenomas usually showed round, slightly high density shadows. Cystic change and enhancement after contrast medium were common. The CT scans of craniopharyngiomas usuallyshowed suprasellar low density shadows with ring enhancement, Large cysts and calcifications were present in most cases. CT scans of other lesions are also analyzed. CT scanning is useful in the differential diagnosis of lesions in this region, however other Roentgenological examinations and clinical manifestations should also be considered as well. A brief discussion is made for improving the accuracy of diagnosis.
