Upper lobe cavity with intracavitary mass: an unexpected diagnosis

Description

A 77-year-old man, with diabetes and a smoker, with no other medical history, presented with cough with sputum and chest pain that had started 2 months earlier. He had no fever, no haemoptysis and no constitutional symptoms. He had a diminished murmur on right chest auscultation and reported of ipsilateral pleuritic pain. Routine blood tests were unremarkable. The chest X-ray (figure 1) showed a right upper lobe cavity with air-crescent in the periphery of a mass inside. It was better characterised with CT (figure 2) that showed an upper lobe cavitary mass with intracavitary content and adjacent pleural thickening. The mass showed no cleavage plane with the thoracic wall. Despite being highly suggestive of invasive aspergilosis (aspergiloma),12 the differential diagnosis included other fungal infections, mycobacterial infection and neoplasm.
