Post-tuberculosis mycetoma: bronchoscopic removal.

A 76-year-old male non-smoker presented to our institution with cough and haemoptysis. He had been treated for cavitatory pulmonary Mycobacterium tuberculosis of the right upper lobe 10 years previously. Chest radiograph and subsequent computed tomography (CT) of the chest demonstrated a right upper cavity containing a mass suspicious for mycetoma. Flexible bronchoscopy under conscious sedation demonstrated a mass obstructing the anterior segment of the right upper lobe. The abnormality was subsequently removed using a flexible endobronchial cryoprobe. Histopathological analysis demonstrated abundant fungal organisms morphologically consistent with Aspergillus species. Microbiological culture of the bronchoalveolar lavage (BAL) from the cavity isolated both Aspergillus fumigatus and Staphylococcus aureus. The patient was commenced on the anti-fungal drug posaconazole and received a course of flucloxacillin. Three months later, there was no endobronchial obstruction and lavage of the affected cavity again isolated Staphylococcus aureus without Aspergillus species. Repeat thoracic CT and flexible bronchoscopy demonstrated no further re-occurrence of the mycetoma at 3 months.
