Plain-English summary
A 21-year-old Thoroughbred mare was put to sleep because she had severe lameness. During the examination, veterinarians found many red, raised bumps on the surface of her small intestine and ovaries. These bumps were made up of blood vessels filled with red blood cells and clotting material, which led to a diagnosis of angiomatosis, a condition involving abnormal blood vessel growth. This case is notable because it is the first time such a condition has been reported in a horse's intestines and ovaries.
Abstract
Dozens of red, raised nodules scattered along the serosal surface of the small intestine and the right and left ovaries were observed as incidental findings on gross examination in a 21-year-old Thoroughbred mare euthanatized for severe lameness. Histologically, these nodules were composed of numerous, variably sized, redundant vascular profiles filled with red blood cells and fibrin thrombi. Based on the presence of multiple nodules composed of benign vascular channels scattered within the small intestine and ovary, a diagnosis of angiomatosis is proposed. To the authors' knowledge, this is the first report of small intestinal and ovarian angiomatosis in a horse.
