Figure 8a. Amniotic fluid embolism in a 40-year-old woman. The patient experienced sudden respiratory distress shortly after giving birth by cesarean section. (a) Radiograph shows bilateral widespread airspace consolidation. Endotracheal intubation was performed. (b) On a follow-up radiograph obtained 3 days later, the extent of the parenchymal areas of increased opacity has decreased. A chest tube was inserted into the right pleural space to relieve the right pleural effusion.
