Orbital inflammation is a common problem in dogs, accounting for the majority of all orbital diseases. Its clinical signs include exophthalmus, enophthalmus, strabismus and reflex disorders. The authors describe the use of MRI in four cases in which there was intracranial extension through the optic canal, orbital fissure or alar canal. The condition was best observed through an abnormal signal increase at the orbital fissure on transverse T2 weighted images, on dorsal STIR images, or on postcontrast transverse or dorsal images.
