%X Mucormycosis is an invasive fungal infection that can result in severe lung infections, with pulmonary mucormycosis (PM) being one of the most prevalent manifestations. Prompt diagnosis is crucial for patient survival, as PM often exhibits rapid clinical progression and carries a high fatality rate. Broncho-alveolar lavage fluid or endobronchial biopsy (EBB) has been commonly employed for diagnosing PM, although there is limited mention of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the literature. In this report, we present a case of PM in a patient with diabetes. While EBB did not yield evidence of Rhizopus infection, a definitive diagnosis was obtained through EBUS-TBNA. The patient underwent combination therapy, including oral medication, nebulization, and EBUS-guided intrafocal amphotericin B injection, which resulted in significant improvement following the failure of initial therapy with amphotericin B injection cholesterol sulfate complex. Our case highlights the potential of EBUS-TBNA not only for mediastinal lymphadenopathy but also for obtaining extraluminal lesion specimens. Furthermore, for patients with an inadequate response to mono-therapy and no access to surgical therapy, the addition of EBUS-guided intralesional amphotericin B injection to systemic intravenous therapy may yield unexpected effects.
