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.
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]
Symptoms of intestinal ischemia vary and can be acute (especially if embolic), [11] subacute, or chronic. [12] Case series report prevalence of clinical findings and provide the best available, yet biased, estimate of the sensitivity of clinical findings. [13] [14] In a series of 58 patients with intestinal ischemia due to mixed causes: [14]
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]
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.
Primary vascular causes of bowel infarction, also known as mesenteric ischemia, are due to blockages in the arteries or veins that supply the bowel.Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis.
Common causes of an acute abdomen include a gastrointestinal perforation, peptic ulcer disease, mesenteric ischemia, acute cholecystitis, appendicitis, diverticulitis, pancreatitis, and an abdominal hemorrhage. However, this is a non-exhaustative list and other less common causes may also lead to an acute abdomen. [3]
