Orbital Choristoma in a Jaguar (Panthera onca).

Advanced imaging and multidisciplinary approach essential for diagnosing rare orbital pathologies in exotic felids.

This case report documents the first orbital choristoma diagnosis in wild felids, specifically in a 2-year-old male jaguar (Panthera onca). The animal presented with classic orbital pathology signs including unilateral periorbital edema, strabismus, exophthalmia, epiphora, and conjunctivitis. Diagnostic confirmation required a multimodal imaging approach utilizing ultrasound, computed tomography, and cytological analysis alongside routine physical and ophthalmic examinations. The cystic structure was surgically excised, with histopathology definitively confirming a choristomatous cyst of lacrimal or conjunctival origin. The surgical intervention resulted in complete recovery without complications or recurrence, demonstrating successful management. This case emphasizes the importance of advanced diagnostic imaging and interdisciplinary collaboration when encountering rare orbital pathologies in exotic felids. Choristomas, benign heterotopic tissue growths, are uncommon in veterinary medicine, particularly in wild carnivores, making this documentation valuable for practitioners managing similar presentations.
