Prognosis | Good[3] |
The cause is often unclear; though may occur secondary to infections or inflammatory bowel disease.[3] Infections involved may include Epstein-Barr virus and Yersinia enterocolitica among others.[3][4] Often it occurs after an upper respiratory infection or gastroenteritis.[3] Diagnosis may be supported by ultrasound or CT scan, after ruling out other possible causes.[1][2][4] Other conditions that appear similar include appendicitis.[3]
No specific treatment is required, though intravenous fluids or NSAIDs may help with the symptoms.[3] Recover may require a few weeks.[3] It is relatively common, occurring most commonly in children or young adults.[5][1] One trial found that nearly 20% of cases that appeared to be appendicitis were in fact mesenteric adenitis.[3] The condition was first classified in 1926.[2]
