Zygomatic Sialolithiasis Diagnosed with Computed Tomography in aDog

[摘要] References(27)A 10-year-old castrated Shih-Tzu male dog was referred for examination of acuteright exophthalmos, protrusion of the third eyelid and soft tissue swelling ventral to theglobe. Ultrasonography revealed echogenic fluid around the right globe. Computedtomography (CT) showed an enlarged right zygomatic salivary gland compared with the leftzygomatic gland and an amorphous cystic mass ventral to the right globe. Hyperdensematerial, which we suspected to be a sialolith, was identified in the right zygomaticgland. The zygomatic gland and the cystic lesion were removed, and a zygomatic sialocelewith sialolith and ductal obstruction were found by histopathological examination. CT wasa useful diagnostic tool for zygomatic sialolithiasis.
