Abstract
Objective: To investigate theCT and M RI features of inflamm atory m yofib rob lastic tumor(M T )and their valie in 1he clinical diagnosis .M e1hods: The CT and M RI findings of 20 cases with pathology proven M T were retrospectively analyzed .of which ,13 cases had CT and 5 cases had M RI.Results:The anatom ic locations of tumors in these 20 patients included lung ( n = 8), epigbttis( n = l), nasal cavity ( n = l), popliteal fossa( n = l), chest wall( n = 2) , buttocks( n = l) , mandib-ularm ohr( n = l), b]adder( n = l) , superficial soft tissue( n = 3) . In term s of ling lesions, there were 3 central lesions presented as solid m asses w ith obscure boundary m argin ; 5 peripheral lesions as solid m asses or nodules w ith w eU-defined m argin . T he lesions out of the ling presented as solid m asses or nodules in diverse sites. MRI appearance w as m ass of a slightly-long Tl slightly-long T2 signal.After contrast enhancem ent,moderate or m arked hom ogeneous or heterogeneous enhancem ent w ere show n in 1he solid part of turn or, cystic and necrotic w iihout m arked enhancem ent. Turn ors w ere m ainly com posed of spindle shaped fibrous cells and inflam m atory cells on pathology . 0 n in m unohistochem istry staining, positive expression of m uscle deriving proteins was observed . Conclusion : The final diagnosis of M T relies on pathology and in m unohistochem istry study, C T and MRI exam inatbn provides inform ation of accurate anatom ic location and are het>ful for the clinical diagnosis.关键词
