Case Discussion

Sialolithiasis is most common disease of salivary glands, accounting for about half of all major salivary gland pathology.

The vast majority of stones involve the submandibular gland, with only a small proportion involving the parotid gland.

The gland may be evaulated with various imaging modalities including; ultrasound, sialography (fluroscopic), CT and MR sialography.

Fluroscopic stone retrieval may also be undertaken.
