title: [Rounded atelectasis in the computerized tomographic image].
abstract: The rounded (helical) atelectasis is a benign alteration of the lung that can be diagnosed by radiography. Besides the criteria of the chest x-ray film and of the conventional tomogram (shadow close to the pleura, located mainly in the inferior lobe, with "comet-sign" and pleural thickening) the most important finding in computed tomography is the "octopus-sign".
