Exogenous Lipoid Pneumonia Induced by Aspiration of Insecticide

Abstract

Exogenous lipoid pneumonia is a rare disorder caused by inhalation and/or aspiration of oil-based substances. The confirmed diagnosis of exogenous lipoid pneumonia is difficult, especially in cases for which it is impossible to ascertain a history of inhalation or aspiration. We present a case of exogenous lipoid pneumonia due to aspiration of insecticide, for which the computed tomography findings of fat attenuation within the lesion were helpful in reaching a correct diagnosis.

Fire-Eater’s Lung

“…WBC was 7.96 × 10 6 /mm 3 , neutrophil count 74%. CRP was only slightly elevated www.journals.viamedica.pl commit suicide, one of those patients drank some amount of insecticide fluid containing petroleum as a solvent [7].…”

“…The radiologic lesions have to be differentiated mainly with inflammatory lesions and with neoplastic disease [1,2,5,7].…”

“…Some intentional uses are also reported [4,5,7]. The first description of FEL was done by Gerbeaux et al [8] in 1971.…”

Acute exogenous lipoid pneumonia caused by accidental kerosene ingestion in an elderly patient with dementia: A case report

“…Acute ELP is secondary to accidental aspiration of a large quantity of lipid material over a short period of time, whereas the chronic form results from long‐term recurrent inhalation exposure to oil products, such as mineral oil for laxatives 5 . Previous literature of acute ELP are limited to unintentional intake in the pediatric field, suicidal attempts and “fire‐eater's lung” in performers who use petroleum derivative for flame blowing 6–8 . To the best of our knowledge, no cases of acute ELP caused by accidental ingestion in an elderly patient with dementia have been reported, although several studies on unintentional intake in the elderly population are available in the literature 3,4 …”

“…However, we did not carry out histopathological examinations considering the possible procedural complications in a demented patient. In most previous studies, the diagnosis of acute ELP is based mainly on an episode of ingestion of lipid material with consistent radiological and cytological findings, and not on histopathological findings 6–9 . This is because the clinical history is relatively clear, and acute ELP shows rapid improvement over a short period of time.…”
