sialolith

Salivary duct lithiasis is a condition characterized by the partial or total obstruction of a salivary gland or its excretory duct due to the formation of sialoliths. A 9-year-old female donkey, belonging to the unique and endangered indigenous breed of donkey in Portugal, was diagnosed with a sialolith in the rostral portion of the right parotid duct based on clinical, oral, dental, and radiographic examination results. Surgical removal of the sialolith was done through a percutaneous approach.
