title: CT-guided fine needle aspiration biopsy of orbital optic nerve tumors.
abstract: Biopsies were done for seven patients who had blinding optic nerve tumors or inflammations, using the fine needle aspiration technique guided by the CT scan. Cytologic material was recovered in this manner in all cases, which allowed the rendering of diagnoses. This allowed for therapeutic planning with minimal therapeutic invasion.
