During childhood, an acute pneumonia with bulging margins usually reflects an abundant production of exudate. However, an unexplained persistence of an expansile pneumonia following therapy indicates that the infectious process may be isolating itself by forming an abscess. Previous reports emphasize that such abscesses are rarely diagnosed prior to thoracotomy or autopsy. Computed tomography facilitates an earlier disclosure of an abscess or empyema that is producing a persistent but unexplained expanding opacification on plain film.
在儿童时期，边缘膨出的急性肺炎通常反映出渗出物大量产生。然而，治疗后扩张性肺炎持续存在且原因不明，这表明感染过程可能正在通过形成脓肿而自行局限。既往报道强调，此类脓肿在开胸手术或尸检前很少被诊断出来。计算机断层扫描有助于更早地发现脓肿或脓胸，这些病变在平片上表现为持续存在但原因不明的进行性模糊影。
