title: Synovial sarcoma of the parapharyngeal space: CT and MRI.
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.
