垂体MRI成像在儿童矮小症的应用

Application of pituitary MRI In children short stature

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。

Objective To investigate application of pituitary magnetic resonance imaging（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）yeats were retrospective reviewed. Results Pituitary adenoma were showed in 9 cases （7.03%） including 6 microadenoma eases; 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 eases（ 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.
