===Description===
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, less commonly 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.

Lipomas are often multiple in number and attach to the mesentery of the intestine via a stalk or pedicle of varying length. The stalk becomes wrapped around a segment of small intestine, causing compression of the intestinal lumen and corresponding mesenteric vessels. Longer stalks are associated with more severe and complete intestinal strangulation. More rarely, broad-based tumours arising close to the intestine can occur causing periodic restriction of ingesta without intestinal compromise. Lipomas may also be incidental findings at post mortem or exploratory laparotomy.
