A Case of Pulmonary Foreign Body Granulomatosis Secondary to Intravenous Injection of Acetaminophen/Oxycodone.

Foreign body granulomatosis is a rare complication of intravenous injection of pulverized oral prescription tablets. We present the case of an active duty male who was ultimately diagnosed with foreign body granulomatosis caused by the crushing and intravenous injection of acetaminophen with oxycodone (Percocet). The 24-year-old patient initially presented with multiple syncopal episodes, hemoptysis and hypoxia. The patient presentation and imaging findings involved in foreign body granulomatosis can mimic many pulmonary disorders and can be widely variable. Diagnosis is made following lung biopsy. The disease has irreversible effects and patients usually have a progressive decline in pulmonary function. Treatment is supportive although lung transplantation may be beneficial in patients with end-stage lung disease. Pulmonary foreign body granulomatosis should be considered in patients presenting with unexplained hypoxia and imaging consistent with diffuse micronodular disease.
