Abstract

An elderly woman with a 1-year history of pulmonary shadows was admitted because of intermittent cough and sputum production for 2 months. Chest computed tomography (CT) scans showed bilateral consolidations and ground-glass opacities, with areas of low attenuation inside consolidative opacities on the mediastinal window. Previous history of radiotherapy for nasopharyngeal carcinoma and long-term use of a compound menthol nasal drops provided were important clues to the diagnosis. CT scan-guided needle lung biopsy and bronchoalveolar lavage were performed, and lipid-laden macrophages were confirmed in both bronchoalveolar lavage and lung tissue. Final diagnosis of exogenous lipoid pneumonia was made on the basis of her risk factors for aspiration, history of oil exposure, and classic radiological and histopathological features. Symptoms improved after discontinuation of causative exposure. It is important for clinicians to raise awareness of exogenous lipoid pneumonia and other aspiration lung diseases.

本文报道1例老年女性患者,主因“体检发现肺部阴影1年,咳嗽咳痰2个月”就诊。患者胸部CT提示双肺实变及磨玻璃影,纵隔窗可见实变内部低密度影,既往因鼻咽癌放疗及长期薄荷油滴鼻病史为诊断提供重要线索,通过肺穿刺活检病理及支气管镜肺泡灌洗证实为外源性脂质性肺炎,停用滴鼻油后症状好转。本患者的诊治过程提醒临床医生应重视对误吸危险因素的识别和管理,提高对误吸相关肺部综合征的认识。.
