“…[2][3][4] Ischemic necrosis or other means of damage to lipocytes results in release of lipase, cholesterol, or other reactive materials, perpetuating a vicious cycle of inflammation. 2,6,16 The relationship between overconditioning and lipogranulomatosis in the bird of this report is unclear. Abundance of fat alone is not sufficient to precipitate lipogranulomatosis in cattle or panniculitis in humans, although an abundance of fat can be envisioned to influence the resultant severity of clinical signs associated with fat necrosis and inflammation.…”

“…[1][2][3][4][5] Depending on the amount and location of affected adipose tissue, it may be an incidental finding or mistaken for tumors or fetal structures, or it may cause obstruction of gastrointestinal, urinary, or reproductive tracts. [1][2][3][4][5][6][7] Most common-ly, death is the result of intestinal tract obstruction by constricting bands or masses of necrotic fat. 1,3,6,7 Disease has been sporadically reported in canine and feline patients.…”

A 28-year-old, female umbrella cockatoo (Cacatua alba) was evaluated because of lethargy, anorexia, regurgitation, and coelomic swelling of 6 month's duration, which corresponded to cessation of egg laying. Radiographs and ultrasound examination demonstrated extensive deposits of coelomic fat and an enlarged oviduct. Exploratory celiotomy demonstrated copious amounts of firm, nodular fat completely surrounding the gastrointestinal tract, resulting in extensive chronic adhesions between intestinal loops. Free yolk was present in the cranial left coelom, yolk coelomitis was diagnosed, and a salpingohysterectomy was performed. Two days after surgery, the bird stopped passing feces and began regurgitating after eating, and a colonic obstruction was demonstrated via contrast radiography. Euthanasia was elected, and necropsy revealed an obstruction of the distal colon caused by extraluminal compression by adhesions of firm, nodular fat. Histologic examination demonstrated extensive fat necrosis with granulomatous inflammation, characterized by cords of necrotic fat surrounded by multinucleated giant cells and epithelioid macrophages with scattered lymphocytes and plasma cells and rare heterophils. The clinical signs, gross lesions, and histologic lesions are characteristic of massive fat necrosis (lipogranulomatosis) in ruminants and mesenteric panniculitis in humans and companion mammals. This is the first report, to our knowledge, of this disease in psittacine birds.

“…Os sinais clínicos associados em geral são conseqüências da estenose ou compressão de algumas estruturas, podendo resultar em uma variedade de síndromes clínicas tais como: estenose intestinal, retenção urinária, distocia e infertilidade (FORNEY et al, 1969;WILLIAMS et al, 1969;BARKER, 1993 (ARBUCKLE, 1962;BRIDGE & SPRATLING, 1962;ITO et al, 1968;FORNEY et al, 1969;WILLIAMS et al, 1969;VÍTOVEC et al, 1975; MOTOI et al, 1984;BARKER, 1993;EL-SEBAIE & EL-AMROUSI, 1995;KATAMOTO et al, 1996a;KATAMOTO et al, 1996b;MYERS & MCGAVIN, 2007).

“…Havia também obstrução da luz vascular com proliferação da túnica média de arteríolas do tecido adiposo. O aumento do tecido adiposo resultante do consumo excessivo de energia durante a fase de crescimento pode ser associado com distúrbios circulatórios e subseqüente degeneração dos capilares sangüíneos (ITO et al, 1968).…”

“…Massive fat necrosis is readily recognised by the chalky white, lumpy to granular nodules of altered fat scattered within normal fat tissue. 2,3,[5][6][7][8] In this form, necrosis may occur in any portion of the omental, mesenteric, and retroperitoneal fat. The masses may vary from small nodules to large solid masses which are encapsulated by fibrous tissue, and which on cut section are firm, dry, and caseous, or sometimes moist, oily, and deep yellow.…”

Clinical, radiographic, and pathological findings of diffuse mesenteric lipodystrophy in a 3-year-old, female domestic short-haired cat are described. The animal had fallen from a height of approximately 20 metres 6 weeks previously, after which it developed respiratory distress and anorexia. The cat was thin, exhausted and had rapid, shallow, open-mouthed breathing. Serial upper gastrointestinal contrast radiographs showed a prolonged transit time of the contrast medium due to restricted gastric emptying, and filling defects of the duodenojejunal portions of the small intestines. The cranial abdominal cavity contained large, firm, white masses that adhered to most of the anterior abdominal organs. The intestinal walls were completely surrounded by large, hard, lobulated masses of lipomatous tissue. The masses were characterised histologically by extensive areas of coagulative necrosis of adipocytes containing foci of saponification. The lesions resembled those of massive fat necrosis or lipomatosis in cattle, pigs and deer.
