9y FS Cocker Spaniel with left‐sided exophthalmos. The left zygomatic salivary gland (a–f: large arrow) is markedly enlarged and is T1
hypointense and T2 hyperintense to the contralateral gland (a–c: small arrow). The contrast‐enhanced images reveal that the glandular
architecture is retained, including the arborizing ductal pattern, suggesting diffuse inflammation rather than neoplasia. Clinical signs
resolved with antibiotic and anti‐inflammatory therapy.

1y MC Pembroke Welsh Corgi with pain on
palpation of left ear. The left parotid salivary
gland, ventral and lateral to the ear canal,
is enlarged and thickened compared to the
right side. There is intense contrast enhance-
ment on transverse images (a: arrows), which
correlates with the contrast‐enhanced gland
on the 3D images (b: arrows).
