title: FDG-PET imaging in Pneumocystis carinii pneumonia.
abstract: The authors present a case of a 26-year-old man, under investigation for Cushing syndrome, who presented acutely with a dry cough and fever. The blood tests were unremarkable apart from a moderate to severe leukopenia. Imaging tests were suggestive of an atypical pneumonia, which was proven to be Pneumocystis carinii pneumonia (PCP) on cytology examination of a bronchoalveolar lavage (BAL). The acute lung changes were demonstrated on a whole-body F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) study. After treatment, a follow-up study showed complete resolution of these changes. The authors suggest that FDG PET may have a role to play in the diagnosis and, in particular, the monitoring of PCP in immunocompromised patients.
