MR images of six synovial sarcomas of the head and neck were evaluated to determine their characteristic sites of origin, size, extent, intensity, and contrast enhancement. It was hoped that specific MR characteristics could be defined to suggest this entity.
A nonmucosal head and neck mass that is isointense to gray matter on T1-weighted images and is well defined yet heterogeneous, with septations, hemorrhage, cysts, calcification, or multilocularity, should raise suspicion of a synovial sarcoma. Because the appearance of synovial sarcomas varies and other masses may appear similar, no specific imaging characteristics define the entity.
对6例头颈部滑膜肉瘤的磁共振成像（MR）进行评估，以确定其特征性的起源部位、大小、范围、信号强度及对比增强情况。希望能明确特定的MR特征以提示该病变。
头颈部非黏膜性肿块，在T1加权像上与灰质等信号，边界清晰但不均匀，伴有分隔、出血、囊肿、钙化或多房性，应怀疑为滑膜肉瘤。由于滑膜肉瘤的表现多样，且其他肿块可能有类似表现，因此尚无明确该病变的特定影像学特征。
