What is a mesenteric cyst?

A mesenteric cyst is a sac-like structure filled with fluid that develops within the mesentery. The mesentery is a membrane that connects the intestine to the abdominal wall and supplies it with blood vessels, nerves, and lymphatic tissue. Mesenteric cysts are usually benign (non-cancerous) and do not cause symptoms, but large or multiple cysts can cause abdominal pain, bloating, constipation, or diarrhoea. Treatment for mesenteric cysts typically involves surgical removal if they cause symptoms or are at risk of complications. Diagnosis of a mesenteric cyst involves imaging tests, such as ultrasound or CT scans, to identify the cyst's location, size, and features. In most cases, mesenteric cysts are managed conservatively with monitoring, but symptomatic or complicated cysts require consultation with a healthcare provider for further evaluation and treatment.
