X线显示左胸膜腔积液。积液可能是浆液、血性液、血性浆液，也有可能是乳糜液(少见)，如果脓液渗出将引起脓胸。可见膈下的胃内气液平面。
This radiograph demonstrates fluid in the left pleural cavity. This pleural effusion could result from a transudate (serous effusion) or from hemorrhage (hemothorax), or serous fluid tinged with blood (serosanguinous effusion). This effusion could be chylous (which is quite rare). A purulent exudate at this location may be termed empyema. An air-fluid level is seen in the stomach below the dome of the left diaphragmatic leaf.
