摘要(Abstract):

目的:分析席汉综合征(SS)患者的垂体磁共振成像(MRI)表现,提高影像学检查对该病的诊断水平。方法:50例经临床确诊的SS女性患者行垂体3.0T MRI平扫及增强检查,观察垂体形态、大小及其与周围组织结构的关系。结果:所有病例垂体MRI均表现为空泡蝶鞍,蝶鞍无扩大,垂体柄未见明显偏移,垂体后叶高信号存在;其中38例(38/50)表现为完全性空泡蝶鞍,腺垂体结构完全消失,垂体柄下端呈游离状悬挂于鞍内;12例(12/50)表现为部分性空泡蝶鞍,其中9例(9/12)腺垂体体积均匀缩小,3例(3/12)不均匀缩小,腺垂体呈薄片状改变紧贴于鞍底,其信号未见明显异常。结论:SS患者的垂体MRI表现具有一定的特征性,结合临床及影像学表现可以早期确诊。
Objective: To analyze the MRI manifestation of pituitary in patients with Sheehan's syndrome(SS) in order to improve the level of diagnosis of imaging examination. Methods: 50 female patients with clinically diagnosed SS underwent pituitary MRI 3. 0T plain scan and enhanced examination to observe the pituitary morphology,size and its relationship with the surrounding tissue structure.Results: Pituitary MRI of all patients were all shown as empty sella with high signal of posterior pituitary,and there was no obvious shift in the pituitary stalk. Of all cases of patients,38 cases showed complete empty sella,and pituitary gland structure completely disappeared,with the lower end of the pituitary stalk in a free state hanging in the saddle. The other 12 cases showed partial empty sella,among which 9 cases showed that the volume of the pituitary gland decreased,and the 3 cases showed that the volume the pituitary gland were not uniformly reduced. And the pituitary gland was a thin sheet change close to the saddle bottom,with the signal being normal. Conclusions: The MRI manifestation of pituitary in Sheehan's syndrome has certain characteristics,which can be helpful to early diagnosis if combined with other clinical data.
