title: Pulmonary actinomycosis appearing as a "ball-in-hole" on chest radiography and bronchoscopy.
abstract: A 40 year old diabetic man with pulmonary actinomycosis was admitted to hospital with recurrent haemoptysis. The chest radiograph showed an air meniscus in the left upper lobe, a rare presentation of pulmonary actinomycosis. Bronchoscopic examination revealed a mass in a cavity which has never been reported previously. He underwent lobectomy and the surgical specimen revealed sulphur granules, the typical pathological finding of actinomycosis, without evidence of fungal or mycobacterial infection.
