Abstract:
Objective To investigate the correlation of CT image features of mesenteric fibromatosis and its pathological characteristics.Methods Data of 12 mesenteric fibromatosis proved histopathologically in PLA General Hospital and Jiangsu Taizhou People's Hospital from March 2006 to March 2015 were retrospectively reviewed.Results There were 5 males and 7 females with ages ranging from 13 to 67.On the CT image,the masses varied from 3.9 cm to 33.0 cm in diameter.8 of them were round or oval well-circumscribed masses,and 4 were irregular with blurry border.10 of 12 cases were totally similar density,which was ranged from 27 HU to 39 HU.Contrast enhanced CT scan showed moderate enhancing masses in l0 of 12 cases.Macroscopic examination of these specimens revealed that the sections of 11 were solid,firm,grey and yellowish,and 1 was solid-cystic.On the histopathology,the masses consisted of homogeneous spindle shaped fibroblasts,myofibroblasts and collagen.Tumor cells were embedded in a collagen network interrupted by fibrotic sections.Immunohistochemical analysis revealed that the tumor cells expressed Vimentin,H-caldesmon and β-catenin.Conclusions Mesenteric fibromatosis is a rare disease with characteristic CT images,which were based on their pathological characteristics.CT images form the basis of preoperative diagnosis of this disease.
