Giant-cell tumour of the sphenoid bone: case report.
We report an 18-year-old woman with a giant cell tumour of the sphenoid bone. CT demonstrated a lytic soft-tissue mass arising from the sphenoid body, extending to the left petrous apex and into the nasopharynx. On MRI the tumour had nonspecific signal intensity, but there was contrast enhancement on both examinations. CT was better for showing the extent of the osseous disease, whereas MRI was more accurate as regards soft-tissue extension.
