Successful treatment of large hemoptysis and pseudoaneurysm of the pulmonary artery associated to oesophagomediastinal fistula with amphotericin B cholesterol sulfate complex: A case report

Oesophagomediastinal fistula is uncommon. Oesophageal fistulas, may manifest as recurrent pneumonias. While pulmonary infections can lead to pulmonary artery pseudoaneurysms (PAPs), particularly in fungal infections. PAPs pose a rupture risk, potentially causing life-threatening hemoptysis. We report a unique case of a 45-year-old male who presented with sudden cough, dyspnea, and hemoptysis. Bronchoscopy triggered massive hemoptysis, necessitating emergency embolization. Persistent hemoptysis prompted further imaging, revealing an aneurysmal dilation located next to the spine and infectious lesions, suggesting an oesophagomediastinal fistula. After initiating therapy with Amphotericin B Cholesterol Sulfate Complex and fistula closure, the patient's hemoptysis resolved, with imaging resolution of the PAP. Long-term Voriconazole therapy ensured continued improvement. This case highlights the rarity and severity of such fistulas may be associated with fungal infections and PAPs, emphasizing the importance of prompt recognition, aggressive treatment for favourable outcomes. In this report, we present an illustrative case of a patient diagnosed with pulmonary mucormycosis infection based on characteristic pulmonary imaging findings.image
