The aim of this study was to describe thoracic high-resolution computed tomography (HRCT) findings of reversible amiodarone-induced lung disease (AILD). The thoracic HRCT of 20 symptomatic patients who were considered as having reversible AILD by the medical staff of our institution were retrospectively reviewed. The patient-selection criteria used were the development of new respiratory symptoms while receiving amiodarone, the exclusion of other respiratory and cardiac diseases, and the decrease of both respiratory symptoms and radiological abnormalities after cessation of amiodarone and corticotherapy. The CT data recorded were those usually sought infiltrative lung diseases. The radiological findings using chest film (n=20) and HRCT (n=4) follow-up was noted. All patients had ground-glass opacities, associated with consolidations (n=4), thin intralobular reticulations (n=5), or both (n=11), with a subpleural (n=18) or central (n=2) location. Eight patients had high-density areas and 13 had pleural thickening (n=13). Bronchial abnormalities included dilation (n=16) and wall thickening (n=19). After therapeutic management, the radiological follow-up showed complete (n=17) or incomplete (n=3) improvement. Ground-glass opacities associated with thin intralobular reticulations and/or subpleural consolidations and bronchial abnormalities are common HRCT findings in reversible AILD.

We have shown that nasal allergen challenge can produce radiological changes in the paranasal sinuses. This mainly concerned the ethmoid sinuses.

Bronchial artery dilatation and aneurysm formation is a potential complication of local inflammation, especially in bronchiectasis. When the bronchial artery has an ectopic origin from the inferior segment of the aortic arch, aneurysms may mimick aortic aneurysms. Despite this particular location, endovascular treatment is possible. We report two such aneurysms that were successfully embolized with steel coils.

Retrospectively ECG-gated MDCT is a promising noninvasive technique with which to assess early postoperative patency and anatomy of CABGs.
