- W2354264546 abstract "Objective To study the CT and MRI features of peripheral primitive neuroectodermal tumor(PNET).Methods CT and MRI appearances of 10 patients with PNET pathologically proved were analyzed retrospectively.All cases underwent CT scan and 2 cases underwent MR imaging examination.There were 5 men and 5 women,the age ranged from 11 years to 54 years old(mean 24 years).Results The tumors were located in the chest wall(n=4),abdomen and sinus(n=2,each),cervical vertebra and humerus(n=1,each).The lesions in the chest wall and abdomen appeared as larger masses(5~16 cm in diameter).The masses were circular and lobulated with heterogeneous density and in company with bone destruction or periosteal reaction.The solid masses were enhanced after contrast medium administration.The lesions in the sinus showed the soft tissue mass with bone erosion.The lesions in bone demonstrated local iso-intensity on T1WI,hyper-intensity on FSE T2WI and on FATSAT T2WI.There were distant metastasis in 3 cases.Conclusion The clinical and imaging features of pPNET in chest wall were more specific than in other locations.CT and MRI can showed intra-tumor structure,and are helpful in delineated the extent of tumor,predicting resectability and monitoring treatment." @default.
