Overview

Sclerosing mesenteritis, also called mesenteric panniculitis, occurs when the tissue (mesentery) that holds the small intestines in place becomes inflamed and forms scar tissue. Sclerosing mesenteritis is rare, and it's not clear what causes it.

Sclerosing mesenteritis can cause abdominal pain, vomiting, bloating, diarrhea and fever. But some people experience no signs and symptoms and may never need treatment.

In rare cases, scar tissue formed by sclerosing mesenteritis can block food from moving through your digestive tract. In this case, you may need surgery.
