Abstract

We present the CT and MRI findings of a histologically proven synovial sarcoma arising in the left parapharyngeal space of a 21-year-old man. CT was useful for confirming the presence of calcification within the tumour, which may be a favourable prognostic sign, and in excluding involvement of cortical bone. The CT and MRI findings were, however, nonspecific. MRI was superior to CT for assessing the topographical relationships of the tumour to the vessels and the invasion of neighbouring structures.

摘要

我们展示了一名21岁男性左侧咽旁间隙经组织学证实的滑膜肉瘤的CT和MRI表现。CT有助于确认肿瘤内钙化的存在，这可能是一个良好的预后征象，还能排除皮质骨受累情况。然而，CT和MRI表现并无特异性。在评估肿瘤与血管的局部关系以及对邻近结构的侵犯方面，MRI优于CT。
