Role of computed chest tomography (CT scan) in tuberculous retinal vasculitis
1Department of Ophthalmology, Lilavati Hospital and Research Center, Mumbai, India. retinalsurgeon@hotmail.com
Aim:
To compare computed chest tomography (chest CT) and routine chest X-rays for the detection of pulmonary tuberculosis in patients with presumed tuberculous retinal vasculitis.
Materials And Methods:
Case reports.
Results:
Three patients underwent a detailed workup for uveitis. Routine chest X-rays showed normal lung fields in all cases with abnormal hilar shadows in one case. Chest CT revealed the presence of active tuberculous mediastinitis in all three patients.
Conclusions:
Chest CT revealed the presence, dimensions, and activity of tuberculous mediastinal lymphadenopathy which routine chest X-rays were unable to detect. Thus, chest CT may be the preferred modality for pulmonary evaluation in these patients.
