Radiology corner. Case 45. Noncardiogenic pulmonary edema as a result of urosepsis.

The authors present the case of a patient with noncardiogenic pulmonary edema as a result of urosepsis. We explain the physiologic and radiographic differences between cardiogenic and noncardiogenic pulmonary edema. We also discuss some specific types of pulmonary edema and the radiographic findings that are commonly present. In addition, we define sepsis and the physiologic effect that it has on the alveolar-capillary membrane of the lung. Since Acute Respiratory Distress Syndrome is a major cause of noncardiogenic pulmonary edema, we also explore this pathologic process and look at some of the possible complications of ARDS. Finally, the challenges in the treatment of cardiogenic and noncardiogenic pulmonary edema and the importance of early diagnosis and appropriate intervention are addressed.
