Diagnosis With Brief Discussion
- Diagnosis
- Bilobar Atelectasis (RML and LLL)
- Radiologic Findings
- Chest posterioranterior radiograph shows obliteration of right cardiac border and descending thoracic aorta. Note small left hilum and attenuated vascular markings of left lung with no visualization of normal sized left lower lobar artery. Air-bronchogram in LLL atelectasis is seen. Lateral radiograph shows downward displacement of minor fissure, which is compatible with right middle lobe atelectasis. However, findings compatible with LLL atelectasis could not be seen probably due to the characteristic of total collapse of LLL, which mimic posterior mediastinal lesion on P-A radiograph.
CT scan confirms atelectasis of two lobes.
Bronchoscopy showed no abnormality on central bronchi.
Right middle and left lower lobe were supposed to be peripheral type caused by recurrent and/or long-standing infection since childhood.
