- W2374995889 abstract "Objective:The purpose of our study is to investigate the magnetic resonance imaging features of alveolar soft-part sarcoma(ASPS).Methods:Nine patients with ASPS confirmed by surgery and pathology had MR scanning before surgery,4 patients had enhanced MRI,2 cases had 1H-MR spectroscopy(MRS).The location,size,morphology,enhanced pattern and 1H-MRS appearance of tumors were analyzed and evaluated.Results:The locations of the tumor included thigh(4 cases),leg(2 cases),upper arm(2 cases),gluteus muscles and iliopsoas(1 case).There were 8 tumors located at the deep muscles.The mean size of the tumors was 5.1cm×7.8cm.Five tumors were lobulated in shape,3 tumors had peri-tumoral soft tissue nodules.The signal intensity was homogeneous in 7 cases,with iso-intensity on T1WI and hyper-intensity on T2WI.Cystic degeneration and necrosis were assessed in 2 cases.The solid component of tumors showed marked enhancement on contrast enhanced MRI in 4 cases.MR spectroscopy showed discrete choline(Cho) peak at 3.2ppm.Conclusion:The MRI appearances of ASPS are nonspecific,but malignancy could be suggested in certain degree,which is helpful in the diagnosis before surgery and provides information for treatment guidance." @default.
