Use of whole-body FDG PET-CT to aid in the diagnosis of occult sarcoidosis.
OBJECTIVE
To report a case where combined whole-body Fluorine-18 fluorodeoxyglucose (FDG) PET-CT scanning was used to aid in the diagnosis of a patient with occult sarcoidosis.


METHODS
Case report.


METHODS
FDG PET-CT scanning was performed in a patient who presented with persistent bilateral panuveitis after cataract surgery and had undergone an extensive negative workup.


RESULTS
FDG PET-CT scanning demonstrated extensive mediastinal adenopathy. Biopsy showed a non-caseating granuloma with associated giant cell formation consistent with a diagnosis of sarcoidosis.


CONCLUSIONS
FDG PET-CT scanning generates tomographic scans with excellent sensitivity, spatial resolution, and anatomical landmark identification and may be useful in the workup of idiopathic uveitis.
