Plain-English summary
Hypertrophic osteopathy, a condition that causes abnormal bone growth, was found in three horses and one pony, all between 8 and 21 years old. Among them, there were two female animals, one intact male, and one gelding. In three cases, this condition was linked to serious health issues like lung abscesses, a type of lung cancer, and a tumor in the ovaries, which led to either death or the need for euthanasia. One horse had hypertrophic osteopathy that seemed to be related to pregnancy, but it got better after she gave birth to a healthy foal. Overall, the outcomes were quite serious for most of the animals involved.
Abstract
Hypertrophic osteopathy was diagnosed in 3 horses and in a pony, ranging in age from 8 to 21 years. There were 2 females, 1 sexually intact male, and 1 gelding. In 3 animals, hypertrophic osteopathy was associated with pulmonary abscesses, bronchogenic squamous cell carcinoma, and ovarian granulosa-cell tumor, respectively, and resulted in death or euthanasia. Duration of the condition ranged from 1 to 4 months. In 1 horse, hypertrophic osteopathy was believed to be secondary to pregnancy, and resolved following uncomplicated delivery of a live foal.
