| 摘 要： | 目的：探讨腺泡状软组织肉瘤的MRI表现。方法：9例手术病理证实的腺泡状软组织肉瘤,术前均进行MRI平扫,其中4例行增强扫描,2例行1H-MRS扫描。对肿瘤的发生部位、大小、肿瘤形态、肿瘤的强化和1H-MRS表现进行分析评价。结果：位于大腿4例,小腿2例,上臂2例,臀肌和髂腰肌1例,8例肿瘤位于深部肌群;肿瘤体积平均大小5.1 cm×7.8 cm;5例呈分叶状;3例肿瘤周围有软组织结节;7例肿瘤的信号均匀,呈中等T1长T2信号,2例有囊变坏死;4例增强扫描者,瘤实质明显强化;2例1H-MRS均表现为3.2 ppm出现明显的Cho峰。结论：腺泡状软组织肉瘤的MRI表现缺乏特异性,但在一定程度上能够反应肿瘤的恶性特点,对于术前肿瘤定性诊断和指导临床治疗具有一定价值。 |

| 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 ilio... |
