متن کاملSignificance of CT and MR findings in sphenoid sinus disease.
Disorders of the paranasal sinuses, particularly the sphenoid sinus, can be associated with significant disorders of the optic and other cranial nerves. We examined 100 consecutive routine CT scans, 100 posterior fossa CT scans, and 100 MR scans to look for evidence of sinus disease, especially of the sphenoid sinus. The sphenoid sinus was abnormal in 7% of scans by all methods. Other sinuses w...
متن کاملMelanocytoma of the cavernous sinus: CT and MR findings.
We present the CT, MR angiographic, and histologic findings of a rare primary meningeal melanocytoma of the cavernous sinus. The primary differential diagnosis is between a melanin-containing tumor and an extraaxial cavernous angioma. Radiologic imaging cannot distinguish between the less aggressive primary meningeal melanocytoma and the more aggressive meningeal melanoma.
