[New Latin : Greek atelēs, incomplete (a-, not; see a-1 + telos, end; see telo-) + Greek ektasis, stretching out (from ekteinein, to stretch out : ek-, out; see ecto- + teinein, to stretch; see epitasis).]
Rounded atelectasis may form secondary to chronic pleural disease (often pleural thickening) as a result of mineral dust exposure (asbestos, silica), exudative pleural effusions, pneumothorax, and childhood cancers.
