Abstract

The characteristic radiographic and CT findings of Iobar atelectasis are well known. However, Iobar atelectasis is a dynamic process, and atypical presentations may occur due to a number of different causes. Familiarity with the various typical and atypical radiographic findings of Iobar atelectasis is important for correct diagnosis. The aim of this manuscript is to illustrate the spectrum of radiographic findings of Iobar atelectasis and to correlate the radiographic findings with the CT findings. The review will illustrate examples of typical and atypical Iobar atelectasis, including combined Iobar atelectasis, peripheral Iobar atelectasis, migrating Iobar atelectasis, rounded atelectasis involving the entire lobe and Iobar atelectasis mimicking paravertebral and mediastinal masses.
