“…Therefore, differential considerations were based on published orbital diseases of other species. Exophthalmos with deviation of the globe secondary to a fluctuant mass was most consistent with an orbital cyst of parasitic, 4–12 zygomatic salivary gland, 13–20 third eyelid, 21,22 lacrimal, or Harderian gland 22–25 origin. Other considerations for exophthalmos included orbital neoplasia (primary, extension from nearby structures, metastatic), 26–30 orbital infection or inflammation (tooth root abscess, 31 abscess/cellulitis, 32–34 granuloma, 35 sinusitis, 36 zygomatic sialoadenitis, 37 foreign body reaction, 38,39 parasite migration), 40–42 orbital bone lesions (craniomandibular osteopathy, 20 craniofacial deformity, 24 osteomyelitis), 43,44 vascular anomalies (arteriovenous fistula, 45 orbital varix), 46 congenital abnormality (orbital dermoid) 47 and trauma, 20 (orbital emphysema, 48 fracture, and retrobulbar hemorrhage) 20,49 .…”
