The use of positron emission tomography/CT in the diagnosis of tuberculosis-associated uveitis.
Detection of tuberculosis as the underlying disease in uveitis can be problematic because of the limited sensitivity of conventional diagnostic methods, especially in the case of latent infection. The aim of our study was to evaluate the clinical usefulness of (18)F-fluorodeoxyglucose positron emission tomography/CT ((18)F-FDG-PET/CT) in patients with uveitis and positive interferon-γ release assay. ⋯ In QuantiFERON-positive patients with severe uveitis forms, such as serpiginous choroiditis and occlusive retinal vasculitis, (18)F-FDG-PET/CT is useful to identify lesions appropriate for biopsy and helps to establish the diagnosis and appropriate therapy for presumed tuberculosis-induced intraocular inflammation.
