Exogenous lipoid pneumonia is a rare disease caused by aspiration or inhalation of oily substances.
A 66-year-old male with dry cough (Case 1) and a 38-year-old female with shortness of breath (Case 2) demonstrated ground-glass opacities on chest computed tomography and were diagnosed with lipoid pneumonia based on the confirmation of lipid-laden alveolar macrophages. Both patients habitually performed sesame oil pulling via nasal or mouth washing for several months prior to the diagnosis.
Steroid therapy and bronchoalveolar lavage resulted in improvement in Case 1, and no intensive therapy was required for Case 2. Sesame oil pulling has been rarely been reported to cause lipoid pneumonia.
外源性类脂性肺炎是一种由油性物质误吸或吸入引起的罕见疾病。
一名66岁干咳男性（病例1）和一名38岁呼吸急促女性（病例2）在胸部计算机断层扫描上显示磨玻璃影，并根据载脂肺泡巨噬细胞的证实诊断为类脂性肺炎。两名患者在诊断前数月都习惯通过鼻腔或口腔冲洗进行芝麻油漱口。
病例1采用类固醇治疗和支气管肺泡灌洗后病情改善，病例2无需强化治疗。芝麻油漱口导致类脂性肺炎的报道很少。
