Mesenteric cysts and mesenteric tumors occur in the mesentery, which are the folds of tissue that attach the organs of the body to the inside of the abdominal wall. Mesenteric cysts and tumors are both very rare conditions and are usually discovered on radiologic images (x-rays and CT scans) or during other abdominal surgery.
Pain is usually the only symptom that indicates there is a mesenteric mass present. The physician may also be able to feel the mass. Nausea, vomiting, diarrhea, bloating, and constipation also sometimes occur with mesenteric tumors.
Most mesenteric cysts are benign (nonmalignant, noncancerous), but surgical investigation and analysis of the tissue are imperative. The usual treatment is the surgical removal of the cyst or tumor.
