Rounded atelectasis of the lung: A pictorial review

Rounded atelectasis with atypical computed tomography findings.

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 resectio...

Rounded atelectasis. Clinical experience with 74 patients.

Rounded atelectasis is an atelectasis of a peripheral part of the lung due to pleural adhesions and fibrosis causing deformation of the lung and bending of some small bronchi. From 1970 to 1986, some 74 patients with rounded atelectasis have been seen at the Lung Department. Sixty-four of these patients had been exposed to asbestos. The lesion was secondary to a benign asbestos pleurisy in nine...

The causes of thrombosis at the site of rounded atelectasis

been described in the hiterature,’ this is the first case in which this usually innocuous pleural mass has produced significant morbidity and contributed to a patient’s death. The special features ofthis case include the demonstration of local extrinsic compression of the airway seen on bronchoscopy, postobstructive pneumonia in the occluded segments, and local pulmonary artery thrombosis in th...

Shrinking pleuritis with atelectasis.

During a 10-year period 28 patients with shrinking pleuritis with atelectasis (SPA) were observed and operated upon. This lesion has been given different names in the literature, for instance rounded atelectasis, pleuroma, pulmonary pseudotumour, and lung folding. All patients except two were operated upon because of a diagnosis of pulmonary tumour. However, at operation no tumour was found. Th...
