蝶鞍及其周围病变 CT 影像58例分析

Sellar and juxtasellar lesions:CT analysis of 58 cases

目的：提高相关临床科室对蝶鞍及其周围病变的认识，达到早期确诊。方法：对经手术、病理或临床证实的５８例该区病变的ＣＴ表现进行回顾性分析。结果：肿瘤性病变４８例，其中，鞍内９例，鞍旁３２例，颅底７例；非肿瘤性病变１０例。ＣＴ诊断准确率９３．４％（５４／５８）。临床最常见的首发症状为视力异常。结论：当临床疑有该区病变时，应积极申请ＣＴ检查。必要时可强调指出冠状位增强扫描。

Objective:To promote the identification of sellar and juxtasellar lesions(SJL) for early diagnosis and treatment.Methods:58 cases with SJL,confirmed by surgical histopathology,biopsy and clinic findings,were analysed retrospectively with CT appearence.Results:Among 58 cases,48 were tumorous(9 intrasellar,32 parasellar and 7 at cranial base)and 10 non tumorous.CT correctly diagnosed SJL in 54/58(93.4%).The most common first symptom of SJL was optic abnormality.The value of various CT images in diagnosis was discussed.Conclusions:CT should be used in case as SJL was suspected in clinic,and also coronal contrast scanning if necessary.
