A 37-year-old woman had worked for 4 years in a shell-processing factory where considerable airborne dust was produced cutting and polishing fresh water shells into pearl nuclei. She had a dry cough and dyspnea. Transbronchial lung biopsy showed noncaseating granulomas and cellular intraalveolar infiltrates. High-resolution lung computed tomography (HRCT) showed diffuse small nodules and ground-glass opacities. Hypersensitivity pneumonitis caused by shell dust should be considered in the appropriate clinical setting in a patient with the appropriate radiographic abnormalities.
一名37岁女性在一家贝壳加工厂工作了4年，该工厂在将淡水贝壳切割和打磨成珍珠核的过程中会产生大量空气传播的粉尘。她出现干咳和呼吸困难。经支气管肺活检显示非干酪性肉芽肿和肺泡内细胞浸润。高分辨率胸部计算机断层扫描（HRCT）显示弥漫性小结节和磨玻璃影。在有适当影像学异常的患者中，若临床情况合适，应考虑贝壳粉尘引起的过敏性肺炎。
