A 67-year-old diabetic male developed bilateral pulmonary mucormycosis (PM). After long-term treatment with amphotericin B (cumulative dose of 30.6 g), clinical resolution was obtained, but small radiographic cavitations persisted. A late relapse occurred and bilateral lobectomy led to a definitive cure. Amphotericin B is not able to penetrate properly into PM cavitations. We suggest that persistence of cavitations should lead to consideration of surgery, even after a good response to amphotericin B.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
