[Pulmonary aspergilloma with ring enhancement on chest CT scans].

A 77-year-old man with hemoptysis was admitted to our hospital. A coin lesion in the right middle lung field was observed on a chest X-ray film. Enhanced CT scans of the chest showed the coin lesion with clear ring enhancement. Ring-enhanced mass shadow in cases of pulmonary diseases are very rare. The level of anti-aspergillus antibody in serum was high and the patient was given the diagnosis of aspergillosis. An upper lobectomy was done and aspergillus organisms were found.
