Overview
CT
- Parotid gland CT scan may be helpful in the diagnosis of Sjögren's syndrome. Findings on CT scan suggestive of Sjögren's syndrome include:[1][2][3]
- Abnormal diffuse fat tissue deposition
- Diffuse punctate calcification
- Chest CT scan may be helpful in the diagnosis of complications of Sjögren's syndrome, which include:
- Nonspecific interstitial pneumonia
- Patchy ground-glass attenuation
- Intralobular reticulation with a lower lobe predilection
- Interstitial pneumonia pattern
- Increased reticular markings in a basilar and peripheral distribution
- Areas of subpleural honeycombing
- lymphoid interstitial pneumonia pattern
- Ground-glass attenuation
- Centrilobular and subpleural nodules
- Septal thickening
- Reticular opacities
- Bronchial/bronchiolar thickening
- Thin-walled cysts
- Nodular lymphoid hyperplasia
- Nodular or mass-like consolidation with or without air bronchogram
- Follicular bronchiolitis
- Centrilobular and peribronchial noduleS
- Nonspecific interstitial pneumonia
