“…Rounded atelectasis is a retraction and folding of the lung occurring in various pleural disorders associated with a retractile fibrosis of the visceral pleura secondary to pleural effusion [8,41,42]. Benign asbestos pleural effusion may be the initial event that results in visceral pleu-ral fibrosis and rounded atelectasis [4,43].…”

The aim of this study was to investigate by computed tomography (CT) whether asbestosis, diffuse pleural thickening and/or pleural plaques are statistically associated. We also tried to find criteria to differentiate between diffuse and circumscribed pleural thickening. From 231 exposed workers, only those subjects whose radiograph showed neither bilateral calcified pleural plaques nor small pulmonary opacities higher than 1/1 grade according to the 1980 International Labour Office (ILO) Classification were considered. Scans were assessed for the presence of subpleural curvilinear lines, septal and intralobular lines, parenchymal bands, honeycombing, rounded atelectasis, pleural plaques and diffuse pleural thickening. CT scans revealed pleural and/or lung abnormalities in 99 workers. Pleural plaques were unilateral in one-third of cases with plaques. Diffuse pleural thickening, parenchymal bands and rounded atelectasis were unilateral in, respectively, 62 and 69 and 75% of cases with the abnormality. Septal and intralobular lines, and honeycombing were always bilateral. CT signs could be grouped into three patterns: 1) septal and intralobular lines, and honeycombing corresponding to pulmonary fibrosis; 2) pleural plaques corresponding to parietal pleural fibrosis; and 3) diffuse pleural thickening, rounded atelectasis and parenchymal bands corresponding to visceral pleural fibrosis. In these workers with a normal or near-normal radiograph, three groups of subjects with different responses were distinguished. Crow's feet and rounded atelectasis help to differentiate plaques from diffuse thickening.

“…CT Signs for Diagnosis of Rounded Atelectasis MAJOR SIGNS (1) A rounded peripheral lung mass 4-7cm in diameter (2) A mass most dense at its periphery (3) A mass that forms an acute angle with the pleura (4) Pleural scarring thickest at locations adjacent to the mass (5) Vessels and bronchi curving in towards the mass (6) At least two sharp margins (7) The presence of a "comet tail" usually good, many reports have agreed that a biopsy of this lesion is not necessary (8, ll, 12). In recent years, asbestos-related rounded atelectasis has been reported (13)(14)(15)(16). It is well known to increase the risk of malig nant diseases (17); several asbestos-related rounded atelectasis cases in conjunction with lung cancer have been reported (18)(19)(20).…”

Rounded Atelectasis with Pleuritis: Diagnosis and Surgical Treatment.

et al. 1992

A 73-year-old male was admitted with a large rounded atelectasis with pleural effusion. The involved lung was refilled with air as soon as surgical decortication of the thickened visceral pleura covering it was performed. Surgical treatment is believed to be necessary when a large rounded atelectasis with pleural effusion persists for a long time, or when malignancy is not completely excluded.

“…The typical radiographic manifestations of asbestos-induced pleural lesions are distinctive [5,6], but the diagnosis of early mesothelioma in patients with pleural thickening may be difficult. Classically, folding and shrinking of the lung, and rounded atelectasis [8][9][10][11][12] are ascribed to fibrosis of the visceral pleura. Benign asbestos pleural effusion may be followed by pleural thickening or fibrosis, but rarely by the development of pleural mesothelioma [13].…”

“…Again, the diagnosis of asbestos-related pleural disease should be favoured, because ergolines usually induce a subacute (over months to weeks), not a chronic (over years) illness. Rounded atelectasis and lung shrinking (crow's feet) may be associated with both aetiologies [9,14]. Thoracoscopy is probably unnecessary in any of the three situations above.…”
