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.
