Abstract

|
A 13-year-old spayed female Beagle dog was referred with high intraocular pressure, hyperemia, andexophthalmos of the left eye and underwent ultrasound, which revealed a mass in the ciliary body of the left eye. Magnetic resonance (MR) imaging was ordered to evaluate invasion of surrounding structures and metastasis to thebrain via the optic nerve. On MR imaging, a single, well-defined, smoothly marginated, triangular-to-oval-shaped masswas found. The mass was hyperintense on T1-weighted images and hypointense on T2-weighted images, similar toa previous case of ocular melanoma. The mass originated from the ciliary body and extended from the anterior chamberto the posterior chamber. Slight enhancement was observed in the mass. There was no evidence of invasion intosurrounding structures or the optic nerve, and no sign of metastasis to the brain. The mass was histopathologicallydiagnosed as benign uveal melanocytoma.
