Abstract
The mesentery is the double layer of peritoneum that suspends the small intestine (jejunum and ileum) from the posterior wall of the abdomen. The superior mesenteric artery and its branches, accompanying veins, lymphatic, lymph nodes, the autonomic nerve plexuses, with a larger amount of connective tissue and varying amounts of fat tissue around the root of the mesentery, are located between two layers of peritoneum. Mesenteric panniculitis is a benign disorder that characterised by fat necrosis, chronic inflammation, and fibrosis. Although the aetiology is not clear, it is associated with many diseases, such as previous abdominal surgery, and malignancies. Mesenteric panniculitis may be asymptomatic or accompanied by symptoms such as abdominal pain, abdominal distention, palpable mass, and fever. Laboratory tests are non-specific in diagnosis. Although diagnosis of the disease is usually with ultrasound and abdominal CT is definitive, diagnosis is made by histopathological examination. Usually, symptomatic treatments are administered in mesenteric panniculitis; however, immunosuppressive agents or steroids have also been reported to be effective. In this study, we report three cases admitted to the emergency room with abdominal pain and diagnosed as mesenteric panniculitis, to draw attention to the cause of this rare abdominal pain.
