1. Understand why underlying chronic lung disease, particularly COPD, can cause atypical patterns of pulmonary edema 2. Recognize the appearance of a novel term, “sponge lung”, in describing the radiographic and CT findings of pulmonary edema superimposed on emphysema 3. Understand how “sponge lung” also aptly describes the underlying physiology of pulmonary edema

1. Classic appearance of pulmonary edema on chest radiography and CT imaging 2. Review of findings previously described in the literature of atypical patterns of pulmonary edema in patients with underlying COPD, e.g. regional distribution of edema to the bases 3. A novel description of pulmonary edema superimposed on emphysema termed “sponge lung” due to its characteristic likeness to the appearance of a sponge      a. On radiographs, this appears as diffuse reticular and alveolar opacities with scattered rounded lucencies      b. On CT, this appears as smooth interlobular septal thickening and alveolar consolidation/ground-glass on a background of centrilobular lucencies 4. How “sponge lung” fittingly also describes the underlying physiology of pulmonary edema, i.e. lung parenchyma acting as a reservoir for transudative fluid much like a sponge
