垂体MRI成像在儿童矮小症的应用

摘要

Objective To investigate application of pituitary magnetic resonance imagingv MRI ) examination in children with short stature and discuss the presentation of pituitary lesions on MRI. Methods MR images and clinic data of children with short stature male 83, female 45 ;4 to 15 years old, mean age( 9. 92 ± 2. 82 )years were retrospective reviewed. Results Pituitary adenoma were showed in 9 cases ( 7. 03% ) including 6 microadenoma cases; Anterior pituitary lobe hypoplasia was found in 18 cases ( 14. 06% ); Empty sella was present in 10 cases ( 7. 81% ); Pituitary stalks showed marked thinning in 2 cases( 1. 56% ); The deficiency of bright signals in posterior pituitary lobe were identified in 4 cases( 3. 12% ); Abnormal pituitary morphology were observed in 43 cases ( 33. 59% ) and the remain presented normal pituitary in 85 cases ( 66. 41% ). Conclusions MRI of pituitary in children short stature plays an important role for diagnosis and contributes to definite the etiology from pituitary structure.%目的 探讨儿童矮小症垂体MRI成像的表现和应用价值.方法 128例诊断为儿童矮小症的患儿,男83例,女45例,年龄4岁至15岁,平均9.92±2.82岁,接受垂体MRI扫描,对MRI影像进行分析.结果 128例患儿中垂体腺瘤9例(其中垂体微腺瘤6例),占7.03%;垂体发育不良18例,占14.06%;空泡蝶鞍10例,占7.81%;垂体柄异常变2例(变细、扭曲),占1.56%;垂体后叶缺失4例,占3.12%.垂体形态器质表现异常43例,占33.59%,垂体形态大小表现正常85例,占66.41%.结论 垂体磁共振成像在儿童矮小症的检查中有重要作用,有助于了解病因和协助诊断.
