A pedunculated lipoma is a benign fatty mass originating from the mesentery and is the most-common intra-abdominal tumour of the geriatric horse. A lipoma may lead to obstruction or strangulation of the small intestine, occasionally affecting the small colon. The tumours are seen in all types of horses but mostly in ponies and cob-types. Geldings appear to be at a higher risk compared to mares and stallions, suggesting a possible endocrine aetiology. It is unclear whether the risk of lipoma formation is associated with body condition. | A pedunculated lipoma is a benign fatty mass originating from the mesentery and is the most-common intra-abdominal tumour of the geriatric horse.
