SYNOVIAL SARCOMA OF THE PARAPHARYNGEAL SPACE - CT AND MRI

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 th e tumour, which may be a favourable prognostic sign, and in excluding involvement of cortical bone.
