SAT0554 CLINICAL FEATURES ANALYSIS OF 50 MESENTERIC PANNICULITIS CASES DIAGNOSED BY COMPUTERIZED TOMOGRAPHIC SCANNING

Background: Mesenteric panniculitis (MP) is a chronic idiopathic inflammatory disease that occurs in mesenteric adipose tissue,which lacks of specific diagnostic methods. Objectives: To retrospectively summarize 50 cases of patients with mesenteric panniculitis(MP) diagnosed by CT to improve the clinicians’ understanding of the disease. Methods: The patients with MP diagnosed by abdominal CT were collected from the hospital of Shanxi Medical University from January 2013 to May 2017. The demographic characteristics, clinical features, auxiliary examination, treatment and prognosis were analyzed and summarized. Results: The proportion of men and women was1:0.92, the age of onset was 25 ∼ 85 years old, the average age was (59.1±14.0) years old. Most of the patients presented with abdominal pain, fever, hematuria, and lymphadenopathy.22 cases with tumor, the most common type is lymphoma, 16 cases with abdominal surgery history. There were no special laboratory tests, no patients had mesenteric pathologic biopsy. 6 cases had abdominal CT review, 1 case of who used hormone treatment showed the lesion was significantly absorbed, the remaining 5 cases no significant changes. Conclusion: MP is common in the elderly, the clinical manifestations are diverse, easy to merge tumor, lymphoma more common, abdominal CT is its most important diagnostic means, when found MP, should pay attention to whether the merger with malignant tumors.
