A mesenteric cyst (MeSH C04.182.473) is a cyst in the mesenterium, and is one of the rarest abdominal tumors, with approximately 822 cases reported since 1507. [1] The incidence is between 1 per 100,000 to 1 per 250,000 hospital admissions. [1] Tillaux's triad named after the French surgeon Paul Jules Tillaux can be
A medical triad is a group of three signs or symptoms, the result of injury to three organs, which characterise a specific medical condition. The appearance of all three signs conjoined together in another patient, points to that the patient has the same medical condition, or diagnosis.
Several causes of sclerosing mesenteritis have been suggested such as trauma, prior surgical procedures, autoimmune diseases such as lupus, IgG4-related disease, rheumatoid arthritis, infections such as tuberculosis, cryptococcosis, schistosomiasis, HIV and medicines such as paroxetine and pergolide but their associations with sclerosing mesenteritis are largely speculative with high degree of ...
The extracolonic tumors may include osteomas of the skull, thyroid cancer, epidermoid cysts, fibromas, [4] as well as the occurrence of desmoid tumors in approximately 15% of affected individuals. Desmoid tumors are fibrous tumors that usually occur in the tissue covering the intestines and may be provoked by surgery to remove the colon.
About 10% of cases have a more serious cause including gallbladder (gallstones or biliary dyskinesia) or pancreas problems (4%), diverticulitis (3%), appendicitis (2%) and cancer (1%). [2] More common in those who are older, ischemic colitis, [5] mesenteric ischemia, and abdominal aortic aneurysms are other serious causes. [6]
The amoebae inside the cyst are protected from the stomach's digestive acid. From the stomach, the cyst travels to the intestines, where it breaks open and releases the amoebae, causing the infection. The amoebae can burrow into the walls of the intestines and cause small abscesses and ulcers to form. The cycle then begins again. [citation needed]
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]
Mesenteric pseudocyst, or pseudomesenteric cyst [1]) is a mass in the abdomen that is devoid of any epithelial lining. [2] They are caused either due to trauma or infection. [ 2 ] [ 3 ] The term mesenteric pseudocyst was first used by Ros et al in 1987.
