Plain-English summary
A horse was found to have a mass in its brain that was causing several serious problems. The horse was blind, seemed disoriented and was circling to the right, was very tired, had stopped eating, lost weight, and was leaning against the stall for support. A thorough eye exam showed that both retinas were severely damaged. Sadly, the horse was put to sleep for humane reasons, and an examination after death revealed that the mass was an adenocarcinoma, a type of cancer, likely coming from the lining of the sinus or nearby glands. The treatment did not work, as the horse was euthanized due to the severity of the condition.
Abstract
A space-occupying intracranial mass was diagnosed in a horse. The clinical findings included blindness, circling to the right, apprehension, anorexia, weight loss, and leaning against the stall. On ophthalmoscopic examination, the most striking observation was complete bilateral devascularization of the retinas. The horse was euthanatized and necropsied. Necroscopy revealed the mass to occupy the olfactory and frontal areas of the left hemisphere of the brain and part of the left frontal sinus. Microscopically, the mass was an adenocarcinoma and probably arose from the lining epithelium of the sinus or from the subepithelial glands.
