Unilateral exophthalmia in a European hedgehog (Erinaceus europaeus) caused by a lacrimal ductal carcinoma.

A 5-year-old European hedgehog was examined because of exophthalmos of the left eye. A retrobulbar mass in the ventromedial orbit was suspected and confirmed by a computed tomography scan. Exophthalmos progressed despite systemic broad-spectrum antibiotic therapy.
