Cleidocranial dysplasia (CCD) is a rare (1:1,000,000) congenital condition secondary to spontaneous mutation (40%) or autosomal dominant inheritance (60%) affecting skeletal and dental systems. Hypomineralization of the hypoplastic clavicles and/or cranium is the major feature observed by prenatal ultrasound. Radiologically clavicles are hypoplastic or absent in chest X-ray. Delayed closure of the fontanelle and the skull sutures in pediatric and adolescent population and increased mobility of shoulders in all age groups (exhibited by the ability to bring shoulders close to each other) are prominent clinical diagnostic features of CCD. The diagnosis of CCD is often missed or significantly delayed. The management of CCD involves a multidisciplinary approach and its early diagnosis is essential to select an optimum plan and therapeutic benefit. We present here a case of CCD in a 17-month-old girl referred to us for investigation of below average weight and height gain; we stress on the usefulness of early diagnosis in the management of CCD and discuss current management concepts.
锁骨颅骨发育不全(CCD)是一种罕见的(1:1,000,000)先天性疾病,继发于自发突变(40%)或常染色体显性遗传(60%),影响骨骼和牙齿系统。产前超声检查观察到的主要特征是发育不全的锁骨和/或颅骨矿化不足。放射学上,胸部X线显示锁骨发育不全或缺失。小儿和青少年人群中囟门和颅骨缝闭合延迟,以及各年龄组肩部活动度增加(表现为双肩能相互靠近)是CCD突出的临床诊断特征。CCD的诊断常常被漏诊或显著延迟。CCD的治疗需要多学科方法,早期诊断对于选择最佳治疗方案和获得治疗益处至关重要。我们在此介绍一例17个月大女童的CCD病例,该女童因体重和身高增长低于平均水平前来我院检查;我们强调早期诊断在CCD治疗中的作用,并讨论当前的治疗理念。
