摘要
目的 探讨小儿垂体朗格汉斯细胞组织细胞增生症(LCH)的临床特征和MRI表现。方法 回顾性分析2014年11月~2023年8月经病理证实的23例垂体LCH患儿MRI资料,其中男12例,女11例,年龄1岁~12岁6月(6.72±3.33岁)。观察病变部位、垂体高度、神经垂体是否存在、垂体柄形态、大小、垂体强化方式、垂体/松果伴随病变等,并总结、归纳垂体LCH的MRI表现。结果 首次就诊原因主要为尿崩症,其它就诊症状为顶部包块2例,顶部压痛1例,颈部包块1例。垂体单系统受累16例,其余均为多系统受累,垂体外常累及颅面骨,少见受累部位为肺部、肋骨等。腺垂体明显凹陷、变薄1例,饱满/隆起4例;神经垂体高信号均未见;垂体柄增粗13例,细小2例,另有1例漏斗部线样狭窄、上段结节状增粗,无明显增粗/细小7例;增强后垂体均明显均匀强化;伴随Rathke囊肿/残腔3例,松果体囊肿2例。结论 小儿垂体LCH磁共振表现具有一定特征性,有助于诊断。
Objective To investigate the MRI and clinical characteristics of Langerhans cell histiocytosis(LCH)of pituitary gland in children.Methods We conducted a retrospective analysis the MRI data of the 23 children with pituitary LCH confirmed by pathological from November 2014 to August 2023,including 12 males and 11 females with an average age of 1 year to 12 years 6 months(6.72±3.33 years old).The lesion location,pituitary height,presence of neurohypophysis,pituitary stalk shape,size,pituitary reinforcement,and pituitary/pineal concomitant lesions were observed.The MRI findings of pituitary LCH were summarized.Results The main reason for the first visit was diabetes insipidus,and other symptoms were head mass in 2 cases,head tenderness in 1 case and neck mass in 1 case.Only pituitary was involved in 16 cases,and the rest were multisystem involved.Craniofacial bones were often involved outside the pituitary,and lungs and ribs were rarely involved.The adenohypophyseal was significantly depressed and thin in 1 case and full/bulging in 4 cases.No neurohypophysial hypersignal was found in all cases.The adenohypophyseal was significantly depressed and thin in 1 case and full/bulging in 4 cases.No neurohypophysial hypersignal was found in all cases.There were 13 cases of pituitary stalk thickening,2 cases of fine,1 case of funnel line stenosis,the upper segment nodular thickening,7 cases without obvious thickening/fine.The pituitary was enhanced uniformly after enhancement.There were 3 cases with rathke cyst/remnant cavity and 2 cases with pineal cyst.Conclusion The MRI manifestations of pituitary LCH in children have certain characteristics,which is helpful for diagnosis.
