Primary cavernous sinus malignant lymphoma treated by gamma knife radiosurgery: case report and review of the literature.
Malignant lymphomas originating primarily in the cavernous sinus have not been histologically verified by any authors. The first reported case to our knowledge of primary cavernous sinus malignant lymphoma, initially diagnosed as benign meningioma and treated by gamma knife radiosurgery, is presented. ⋯ Primary cavernous sinus malignant lymphoma is an extremely rare brain tumor, but it must be considered in the differential diagnosis of an enhanced mass in the cavernous sinus. Stereotactic radiosurgery using the gamma knife technique for intracranial brain tumors, especially in the cavernous sinus, is associated with risk, as was seen in our patient. Our experience points out the pitfalls of gamma knife radiosurgery; it should be performed only after histologic confirmation has been obtained.
