The comb sign is a radiological sign seen on computed tomography or magnetic resonance imaging scans, primarily used to identify inflammation in the mesentery. [1] It refers to the appearance of engorged mesenteric vessels resembling the teeth of a comb, which is a key feature seen in several abdominal conditions, particularly those associated with inflammatory bowel diseases, such as Crohn's ...
However, it is not specific and can be found in other conditions such as mesenteric oedema, lymphedema, haemorrhage, and presence of neoplastic and inflammatory cells must be excluded. Mesenteric lymph nodes are rarely larger than 10 mm in sclerosing mesenteritis. Larger lymph nodes should prompt further investigations with PET scan or biopsy. [7]
The mesentery of the small intestine arises from the root of the mesentery (or mesenteric root) and is the part connected with the structures in front of the vertebral column. The root is narrow, about 15 cm long, 20 cm in width, and is directed obliquely from the duodenojejunal flexure at the left side of the second lumbar vertebra to the ...
The misty mesentery sign is a non-specific radiological finding characterized by increased attenuation within the mesenteric fat on computed tomography (CT) imaging. It reflects pathological processes that result in infiltration, edema, or increased cellularity within the mesentery, often in association with inflammation and adjacent lymphadenopathy. [1]
SMA syndrome is also known as Wilkie's syndrome, cast syndrome, mesenteric root syndrome, chronic duodenal ileus and intermittent arterio-mesenteric occlusion. [3] It is distinct from nutcracker syndrome, which is the entrapment of the left renal vein between the AA and the SMA, although it is possible to be diagnosed with both conditions. [4]
“Acute inflammation helps to protect and heal our bodies, however, chronic inflammation is a prolonged state that can damage healthy cells, tissues, and organs contributing to various diseases ...
Early radiation enteritis is caused by cell death of the crypt epithelium and subsequent mucosal inflammation, however usually subsides after the course of radiation therapy is completed. Delayed radiation enteritis is a chronic disease which has a complex pathogenesis involving changes in the majority of the intestinal wall.
One 2024 review found that replacing saturated fats with unsaturated fats like seed oils improves health markers and doesn’t increase inflammation. Plus, there's no reason to fear inflammation ...
