Vertical retrosternal density paralleling the sternum, with haziness of a hemithorax on chest roentgenogram, often challenges the clinical acumen of pediatricians, chest physicians, and pediatric radiologists alike. Its presence has been historically linked to either pulmonary underdevelopment and/or accessory hemidiaphragm. The surgical and radiological pediatric literature has long debated this topic, but unfortunately, it has not received much attention in the general pediatric or in pediatric pulmonology literature. The similar radiologic appearance of these two entities can cause confusion both in diagnostic and the therapeutic approach. Many authors advocate an invasive modality, including thoracotomy, as the only definitive way to differentiate between them. We present two similar cases with retrosternal densities, review the pertinent literature, and propose a rational approach to diagnosis and treatment.
胸骨后垂直密度影与胸骨平行，胸部X线片显示半侧胸腔模糊，这常常考验儿科医生、胸科医生和儿科放射科医生的临床敏锐度。从历史上看，其出现与肺发育不全和/或副半膈有关。儿科外科和放射学文献长期以来一直在讨论这个话题，但遗憾的是，在普通儿科或儿科肺病学文献中并未受到太多关注。这两种情况相似的放射学表现会在诊断和治疗方法上造成混淆。许多作者主张采用包括开胸手术在内的侵入性方法，认为这是区分它们的唯一确切方法。我们展示了两例有胸骨后密度影的相似病例，回顾相关文献，并提出一种合理的诊断和治疗方法。
