Abstract:
Objective To summarize the MSCT signs and the key points of differential diagnosis of sclerosing mesenteritises (SM) which were misdiagnosed by clinical and CT,to reduce the misdiagnosis rate.Methods Clinical and MSCT data of 23 misdiagnosed SM patients were analyzed retrospectively.The misdiagnosed diseases,misdiagnosed causes,and differential diagnosis were analyzed.Results SM were mainly misdiagnosed as tumor and infective inflammation.The main causes of misdiagnosis and differential diagnostic features were listed as follows.(1)SM didn't have specific clinical manifestations.(2)The density of the adipose tissue in mesentery increasedmisty mesentery.A clear demarcation between the lesion and the surrounding normal fatty tissue could be differentiated from infective inflammation.(3)The mass-like false capsule had space-occupying effect of displacement of the surrounding structures.However, the blood vessels were encapsulated by the mass-like false capsule with fat ring around, which could be differentiated from fat-containing tumors.(4)The soft mass was formed at the root of the mesentery.The fat halo sign and mild enhancement of the mass can be differentiated from lymphoma and carcinoid.Conclusion SM is easily misdiagnosed both in clinical practice and medical imaging.Recognition of differential diagnostic features of MSCT can reduce the misdiagnosis rate.
