Background: 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.
Methods: We screened 95 patients with different uveitis forms by QuantiFERON TB-Gold test.
Purpose: The diagnosis of tuberculosis as an etiological factor in patients with uveitis is difficult because of lack of specific diagnostic tests. The authors report 2 cases of occlusive retinal vasculitis, in which (18)F-FDG-PET/CT was helpful for the diagnosis of tuberculosis as a presumptive cause of intraocular inflammation.
Methods: In 2 patients with severe occlusive retinal vasculitis and positive QuantiFERON TB-Gold test, (18)F-FDG-PET/CT, transbronchial needle-aspiration biopsy, and microbiological investigation were performed.
