Zygomatic sialocoele with underlying ductal neoplasia in a cat
Australian Veterinary Journal
|July 19, 2025
Abstract:
A 9-year-old British Short Hair cat presented with a 12-month history of progressive exophthalmos to the right eye. A computed tomography (CT) scan was performed, and it revealed a large 3.1 × 2 × 2.3 cm peripherally contrast-enhancing right retrobulbar mass in the region of the zygomatic salivary gland. Preliminary results of a fine-needle aspirate (FNA) were inconclusive, so the mass was surgically excised via the right partial zygomatic ostectomy approach. Histopathological evaluation was consistent with benign ductal neoplasia of salivary gland origin.

01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
