title: [False images of endobronchial tumor in CT-scan].
abstract: Bronchoscopic identification of an endobronchial foreign body is an unexpected finding in adults. Modern imaging techniques such as computerised tomography (CT) may identify bronchial obstruction but not the cause. Moreover, images may be suggestive of other pathologies, especially when the previous aspiration cases are unknown. The most common CT findings in this setting are atelectasis, lung hyperlucency, localised bronchiectases and lobar consolidation. CT diagnosis of false endobronchial tumors in patients who have swallowed a foreign body is rarely described in the bibliography. In view of the potential adverse outcome in the case of wrong diagnosis we consider it is of interest to report two cases of endobronchial tumors diagnosed by CT in which flexible bronchoscopy allowed identification and extraction of an endobronchial foreign body.
