Significant improvement of visual functions after removal of an intracranial giant optic nerve glioma revealing exophytic growth: case report.

Objective And Importance: Intracranial giant optic nerve gliomas, usually presumed as optic chiasmatic gliomas, are much less common. The architectural tumor form of optic nerve glioma without neurofibromatosis type 1 is usually the expansile-intraneural pattern. The exophytic optic nerve gliomas without neurofibromatosis type 1 are relatively uncommon.

[111In-DTPA cisterno SPECT for the diagnosis of CSF rhinorrhea: case report].

The authors report on a patient with postoperative CSF (cerebrospinal fluid) leakage subsequent to transsphenoidal surgery where cisterno SPECT (single photon emission computed tomography) demonstrated the precise location of a CSF fistula. Seven months after surgery, the patient suffered from CSF rhinorrhea and headache. MRI (Magnetic Resonance Imaging) revealed significant contrast on T1-weighted images resulting from measurements in the right sphenoid sinus, which were hyperintense relative to CSF.
