Overview
Head and neck CT scan is the study of choice for the diagnosis of sialolithiasis. Findings on CT scan suggestive of sialolithiasis include hyperdensity of gland with stranding and enlargement of the gland in acute obstruction. In chronic sialolithiasis, fatty atrophy and reduction in salivary gland parenchymal volume may be seen.

Head and neck CT scan is the study of choice for the diagnosis of sialolithiasis.[2][3][4]
- The following results are seen in acute obstructive due to sialolithiasis after administration of contrast:
- The gland may appear enlarged
- Hyperdensity of gland with stranding
- In chronic sialolithiasis, fatty atrophy and reduction in salivary gland parenchymal volume may be seen.
