Illicit narcotic injection masquerading as acute pulmonary embolism

Abstract

A 23-year-old male presented from a nursing home with hypotension, tachycardia, diaphoresis and electrocardiographic evidence of right ventricular strain that was confirmed by echocardiography. His differential diagnosis included sepsis and pulmonary embolism. A high-resolution computed tomography scan demonstrated no pulmonary emboli but did demonstrate multiple bilateral pulmonary nodules. Upon questioning he admitted to injecting a long-acting narcotic that had been manually macerated, dissolved in saline, and injected through an indwelling intravenous line. Lung biopsy findings were consistent with cellulose-induced perivascular granulomatosis. Cellulose granulomatosis can be seen in patients who inject medications designed for oral use and should be considered in patients who present with acute pulmonary hypertension. © The Author(s) 2013.
