disscusion• The CXR shows bilateral infiltrates and air bronchograms with a perihilar distribution.• The heart size is normal.• There are no Kerley B lines or evidence of upper lobe venous diversion.• All these are typical features of PCP
Case-4• This middle-aged male had low- grade fever of one month’s duration• associated with productive cough and loss of weight.

Case-5• This patient presented with stridor due to thyroid goiter.• was intubated (Fig. 1).• Repeat CXR was done six hours later (Fig.2).• What is the main radiological abnormality?

discussion• The first CXR shows a normal cardiac shadow associated with bilateral perihilar alveolar infiltrates suggestive of acute pulmonary edema.• The development of pulmonary edema with a normal heart size is indicative of an acute event.• The rapid clearance of the pulmonary infiltrates here indicates that the process is rapidly corrected by positive pressure.• In this patient, an important consideration is negative pressure pulmonary edema due to upper airway obstruction from the thyroid Goiter
