窒息性胸廓发育不良的影像表现（附4例报告）

目的：加深对窒息性胸廓发育不良（ATD）影像表现的认识。方法：通过4例ATD X线和CT影像分析，结合临床资料及有关文献加以讨论。结果： ①ATD是一种少见的常染色体隐性遗传性骨软骨发育不良疾病。②X线主要表现：胸廓狭长，肋骨短，肋骨头膨大；髂翼呈方形，股骨头骨骺提前骨化；长骨短，干骺端增宽；掌指骨短粗，锥形骨骺及赘生指。结论：对反复肺部感染的患儿，应进行影像学检查，早日明确诊断，为临床治疗提供依据。

The imaging features of asphyxiating thoracic dysplasia(report of four cases)

Objective: To promote the understanding of the image features of asphyxiating thoracic dysplasia(ATD). Methods: X-ray films and CT image features of four ATD were studied combining with clinical and relative literatures. Result: ATD is an uncommon autosomal recessive hereditary disorder of osteochondrodysplasia. The main findings of ATD are as follows: a narrow thorax, short ribs, the anterior ends of the ribs are widened and cupped; the pelvis also shows flaring ala of the ilium and early ossification of the centers for the capital femoral epiphyses; extremity deformities include shortening of the long tubular bone, metaphyseal irregularities and windening, the shortening of tubular bones of the hands with cone-shaped epiphyses and polydactylism. Conclusion: The children who suffer from pneumonia repeatedly should perform X-ray examination to help make correct diagnosis on time.
