Abstract:
Rounded atelectasis is atelectasis of the peripheral part of the lung, typically in contact with thickened pleura, featuring characteristic computed tomography findings. In this case, a 61-year-old man with history of asbestos exposure presented with a right-middle-lobe nodule on chest radiograph, with computed tomography findings suspicious for neoplasm. The patient underwent surgical resection, which revealed rounded atelectasis. Our case raises a question about the sensitivity of radiographic criteria used in identifying rounded atelectasis, and it emphasizes the need to keep rounded atelectasis in the differential diagnosis of a single pulmonary nodule in a patient with a history of asbestos exposure.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
