“…The mechanical removal of the oil components by alveolar lavage, similar to the method applied for pulmonary alveolar proteinosis, has also been reported to improve severe cases of lipoid pneumonia [ 22 , 23 ]. In Case 1, bronchoalveolar lavage resulted in improvement.…”

BackgroundExogenous lipoid pneumonia is a rare disease caused by aspiration or inhalation of oily substances.Case presentationA 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.ConclusionSteroid 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.

“…According to some authors, prolonged corticosteroids may be effective. [11] Supportive measures, such as oxygen, respiratory therapy, and whole-lung lavage, should be considered [12] or even antibiotics if a secondary infection complicates the lipoid pneumonia, but no consensus exists. In our case no further treatment was necessary after surgery.…”

Rationale:Exogenous lipoid pneumonia is a rare condition due to abnormal presence of oily substances in the lungs. It is a rarely known cause for false positive 18FDG PET-CT results and can sometimes lead to invasive investigations. Searching and finding the source of the oily substance is one of the keys to the diagnosis. Inhalation of oily drugs during snorting has rarely been described.Patient concerns:A patient with well controlled HIV infection was referred for an 18FDG PET-CT to assess extension of Kaposi's disease, recently removed from his right foot. The patient had no particular symptoms.Diagnoses:Abnormal uptake of 18FDG was found in a suspicious lung nodule. An experienced radiologist thought the nodule was due to lipoid pneumonia.Interventions:Bronchoalveolar lavage fluid did not contain lipid-laden macrophages but bronchoscopy showed violet lesions resembling Kaposi's disease lesions. Lobectomy was performed after a multidisciplinary discussion.Outcomes:Anatomopathological analysis revealed the nodule was due to lipoid pneumonia. The patient's quality of life did not diminish after the operation and he is still in good health. The source of the oily substance causing lipoid pneumonia was found after the surgery: the patient used to snort oily drugs.Lessons:The presence of a suspicious lung nodule possibly due to lipoid pneumonia in a patient with known Kaposi's disease was difficult to untangle and lead to invasive surgery. It is possible that if a source of exogenous lipoid pneumonia had been found beforehand, surgery could have been prevented.

“…The acute form of ELP is caused by accidental aspiration of a large quantity of mineral oil in a short period of time. CT scan opacities are typically ground-glass or consolidative and can be seen in most patients within 24 hours [9,10,11]. The chronic form typically occurs in older patients with predisposing anatomic or functional abnormality in swallowing, but it has also been reported in children with cleft palate and mental retardation.…”

Exogenous lipoid pneumonia mimicking multifocal subpleural tumors

et al. 2020

View full text Add to dashboard Cite

Introduction Exogenous lipoid pneumonia (ELP) is caused by inhalation or aspiration of different oily substances of animal, vegetable, or mineral origin. It can be in acute or chronic form. Herein, we report a case of ELP in its chronic form, confirmed in surgical lung biopsy. Case outline A 47-year-old male locomotive engineer, former smoker, without clinical symptoms, with a history of pneumonia two years previously, was referred to our institution. The operating diagnosis of multifocal subpleural tumors was made based on the chest computed tomography. A surgical lung biopsy confirmed a diagnosis of ELP. Conclusion Diagnosis of ELP is frequently made after surgical biopsy performed for suspected neoplasm, because of neglecting profesional exposure to mineral oils.
