Abstract

Diagnostic dilemma of persistent mass-forming parenchymal opacity in the lung periphery occurs occasionally inthe realm of diagnostic radiology. Until recently, literature on the role of CT in peripheral organizing pneumonia, which is difficult to differentiate form malignancy, has little been published. We experienced one caseof pathologically proven organizing pneumonia diagnosed preoperatively by chest CT. When it comes to solitary peripheral mass density in the lung, we think that CT can be proved useful in the diagnosis of benign organizing pneumonia by showing regular and smoothly corrugate margin, peripheral contrast enhancement with inner lowdensity, and air-trapping by intervening normal lung parenchyma.
