| epicardial fat sign | <radiology> Two lucent lines on lateral CXR anterior to heart, subepicardial fat around LAD, anterior mediastinal fat, lines seen in 40% of all lateral CXRs, if separation greater than 2 mm most likely to be consider pericardial effusion or thickening (12 Dec 1998) |
| faecal fat determination | <investigation> A test that measures the amount of fat in the stool and the percentage of dietary fat that is absorbed. This test is used to evaluate potential fat malabsorption syndromes. Stools are collected for 24 hours. Normal values include less than 7 grams of fat per 24 hours, based on a diet of 100 grams of fat per day for 3 days before the test. Decreased fat absorption can be seen in biliary stricture, biliary cancer, celiac sprue, cholelithiasis, chronic pancreatitis, Crohn's disease, cystic fibrosis, acute pancreatitis, pancreatic cancer, radiation enteritis, short bowel syndromes (post surgical) and Whipple's disease.

| yellow fat cell | <pathology> An adipocyte that has asingle big fat droplet and very little cytoplasm. (11 May 1997) |
| familial fat-induced hyperlipaemia | Hyperlipoproteinaemia characterised by the presence of large amounts of chylomicrons and triglycerides in the plasma when the patient has a normal diet, and their disappearance on a fat-free diet; low alpha-and beta-lipoproteins on a normal diet, with increase on fat-free diet; decreased plasma postheparin lipolytic activity; and low tissue lipoprotein lipase activity. It is accompanied by bouts of abdominal pain, hepatosplenomegaly, pancreatitis, and eruptive xanthomas; autosomal recessive inheritance. See: familial lipoprotein lipase inhibitor. Synonym: Burger-Grutz syndrome, familial fat-induced hyperlipaemia, familial hyperchylomicronaemia, familial hypertriglyceridemia, idiopathic hyperlipaemia. (05 Mar 2000) |

Synonym: corpus adiposum buccae, Bichat's fat-pad, Bichat's protuberance, fat body of cheek, sucking cushion, sucking pad, suctorial pad. (05 Mar 2000) |
| fat body of ischiorectal fossa | The fat within the ischiorectal fossa. Synonym: corpus adiposum fossae ischiorectalis, fat body of ischiorectal fossa. (05 Mar 2000) |
| fat body of orbit | The mass of fat contained in the orbit that contributes to the support of the eyeball. Synonym: corpus adiposum orbitae, fat body of orbit. (05 Mar 2000) |
| fat cell | <pathology> An animal connective tissue cell specialised for the synthesis and storage of fat. Such cells are bloated with globules of triglycerides, the nucleus being displaced to one side and the cytoplasm seen as a thin line around the fat droplet. (25 Jun 1999) |
| fat droplet | <pathology> Micro aggregates of (mainly) triglycerides visible within cells. (18 Nov 1997) |
| fat embolism | <orthopaedics> The occurrence of fat globules in the bloodstream following fracture of a long bone, in burns, in childbirth or in association with fatty degeneration of the liver. Symptoms occur when fat globules block vessels within the lung (i.e. Pulmonary embolism) or the cerebral vasculature (i.e. Stroke). Fat embolism after bone fracture generally occurs in the first 3-4 days post fracture and commonly manifests with the signs and symptoms of pulmonary embolism. (27 Sep 1997) |
