“…Moreover, the underdiagnosis of this condition is also frequent, likely due to the absence of clinical signs when the lipomas do not interfere with the functionality of adjacent organs (10). There are many reports of intra-abdominal lipomas in horses (1,8,12). However, we found no report in the literature describing this intrathoracic neoformation in the species.…”

Lipoma is a benign neoplasia originating from adipocytes. It is frequently diagnosed in veterinary medicine and usually presents as cutaneous nodules but can also occur inside body cavities in less common cases. There are several reports of abdominal cavity neoplasia in horses, an important cause of colic in these animals. No cases of neoplasia in the thoracic cavity have been reported for this species. Therefore, the aim of this study was to report an intrathoracic lipoma located in the visceral pleura of an American Quarter Horse. The equine was euthanized after relapses of surgically resolved colic and unresponsive visceral pain. At necropsy, we observed fibrinous peritonitis, adherence of intestinal loops in its abdominal cavity, and hemomelasma ilei in several intestine segments. In the thoracic cavity, a whitish, firm, pendulous structure with a regular surface measuring approximately 4.0 cm x 3.0 cm was observed in the pleura of the right caudal lung lobe–and diagnosed by histopathology as lipoma. Due to the rarity of this type of lipoma presentation and considering the absence of reports of its occurrence in horses, this report is essential to list this neoplasia as a differential in pleural masses in the species.

“…In this case, ultrasound revealed small intestinal loops with thickened walls but not the mass. Considering its position, a combination of transcutaneous and rectal ultrasonography may facilitate the The length of the pedicle reportedly acts as a risk factor rather than the size of the lipoma (7,13). The elongated pedicle allows the mass to move more freely in the abdominal cavity, causing an extraluminal and strangulating obstruction by surrounding the intestine and mesentery (7).…”

A seven-month pregnant 15-year-old Thoroughbred mare presented with acute abdominal pain to Jeju National University Equine Hospital. At presentation, a nasogastric intubation revealed 10 L of gastric reflux; rectal palpation and ultrasound revealed dilated loops and thickening of the walls of the small intestine. An exploratory laparotomy revealed strangulation of the small intestine due to a large abdominal mass. The mass was double-ligated and resected blindly due to the short pedicle. An enterectomy was not performed as intestinal motility was detected following the mass removal. Histopathological examination confirmed that the mass was a lipoma, measuring 24 cm × 16 cm × 16 cm in size. On day 8 post-surgery, the mare was discharged without complications. This case report describes the diagnosis and treatment of strangulation of the small intestine by a pedunculated lipoma, thus providing useful information on lipoma in horses.

“…Mesenteric lipomas typically cause strangulating obstruction of the jejunum when the pedicle wraps around the intestine and its mesentery and constricts the blood supply. Alternative methods for strangulation include strangulation of the mesentery without small intestinal involvement (Bauck et al., 2020), excessively large mesenteric lipomas causing venous occlusion and luminal compression (Verwilghen et al., 2013), and wrapping of two lipomas around each other (Freeman, 2019). A recent theory was proposed wherein the pedicles of these tumours form half‐hitch knots around the intestine (Gandini et al., 2022), but this remains to be clinically verified.…”

SummaryA 19‐year‐old Rocky Mountain Horse gelding was presented for emergency evaluation of colic. A pedunculated lipoma was found to be strangulating the caecum and ileocaecal junction at surgery. Following the resolution of the incarceration, it was found that the pedicle originated on the jejunal mesentery, but the stalk did not appear long enough to have formed a half‐hitch around both the caecum and ileum. The horse was euthanised due to complete caecal devitalisation. A second pedunculated lipoma was identified at necropsy, located on the transverse colon with an area of ischaemia on the mesenteric pedicle (the abnormal stalk of tissue connecting the lipoma to the colonic mesentery), consistent with pressure from being entwined with the jejunal mesenteric pedicle. This report is the first to describe caecal and ileal incarceration and strangulation by a pedunculated lipoma in a horse.
