Overview
There are no diagnostic CT scan findings associated with uveitis. The presence of certain CT findings, in the presence of uveitis, may be suggestive of specific underlying causes such as inflammatory bowel disease[1][2][3], sarcoidosis[4][5], and Behcet's disease[6][7].
CT
There are no diagnostic CT scan findings associated with uveitis. The presence of certain CT findings, in the presence of uveitis, may be suggestive of specific underlying causes.
Inflammatory Bowel Disease
Crohn's disease
The following CT findings are suggestive of Crohn's disease:[1][2]
- Fat halo sign
- Comb sign
- Transmural bowel wall enhancement
- Fistulae
- Skip lesions
Ulcerative colitis
The following CT findings are suggestive of ulcerative colitis:[1][3]
- Inflammatory pseudopolyps
- Fat halo sign
- Lead pipe sign
- Rectal involvement
- Mural stratification
Sarcoidosis
The following CT findings are suggestive of sarcoidosis:[4][5]
- Bilateral hilar lymphadenopathy
- Galaxy sign in pulmonary sarcoidosis
- Panda sign in sarcoid lesions affecting the head
- Liver and spleen nodules corresponding with granulomas appearing as hypoattenuating masses
Behcet's disease
The following CT findings are suggestive of Behcet's disease:[6][7]
- Pulmonary vascular abnormalities (e.g., ectasia, aneurysms, infarction, thromboembolism, venous varices, hemorrhage)
- Features of aortitis
