One of the diagnostic possibilities to consider when a patient presents with cough, fever, dyspnea, or pulmonary infiltrates is hypersensitivity pneumonitis. Some of the problems encountered in diagnosis of diffuse lung disease are illustrated in two case reports. In one of the cases, interstitial pneumonitis of insidious onset was attributed to inhalation of thermophilic organisms in moldy silage. In the other, the outstanding pathologic feature was bronchiolitis obliterans, and circumstantial evidence pointed to a home humidifier as the source of the problem.
当患者出现咳嗽、发热、呼吸困难或肺部浸润时，需要考虑的一种诊断可能性是过敏性肺炎。两篇病例报告阐述了弥漫性肺疾病诊断中遇到的一些问题。其中一个病例，隐匿性起病的间质性肺炎被归因于吸入发霉青贮饲料中的嗜热微生物。另一个病例，突出的病理特征是闭塞性细支气管炎，间接证据表明家用加湿器是问题的源头。
