The case of a @entity1 who presented with @entity1353 and a dry cough six weeks after mediastinal radiotherapy for @entity5 is described. The @entity1 was on @entity229 (30 mg/day) and @entity500 (100 mg/day) throughout the course of radiation. The respiratory difficulties developed as the dose of @entity229 was gradually decreased to 20 mg/day postradiation. Chest x-ray showed @entity358 . Computed tomography scan of the thorax confirmed bilateral ground glass @entity231 , with well-defined lateral margin on the right side corresponding to the field of radiation. However, the airspace @entity231 extended beyond the radiation field into the periphery of the lungs together with mild airway dilation on the left side compatible with @entity3616 ( @entity3616 ) or @entity3616 . Bronchoalveolar lavage performed on the nonirradiated area showed an intense lymphocytosis. No cause of @entity3616 other than radiation was found. Treatment with high dose @entity288 (80 mg/day) resulted in rapid clinical and radiological improvement, and resolution of chest x-ray abnormalities. Focal mediastinal radiation therapy may induce @entity651 including @entity3616 . In addition, the concurrent use of moderate dose @entity229 and @entity500 during the periradiotherapy period does not prevent the development of either @entity3616 or @entity1207 .

@entity288 and @entity500 do not prevent radiation-induced XXXX .
