title: Aspergillus colonisation of pulmonary rheumatoid nodules: a rare cause of 'bull's eye' appearance.
abstract: Pulmonary rheumatoid nodules [PRNs] are a well described manifestation of rheumatoid arthritis [RA]. Fungal colonisation of these nodules is a rare phenomenon. We report a case of Aspergillus colonisation of multiple cavitary rheumatoid nodules in a young female patient with long-standing seropositive RA with 'bull's eye' appearance on computed tomography [CT]. The 'bull's eye' appearance inside PRNs should raise the suspicion of possible fungal colonisation. In patients with RA, a high index of suspicion for the fungal colonisation should be considered by the clinicians treating pulmonary cavitary nodules.
