摘要

Gangliogliomas involving the optic apparatus are rare, with only 23 cases described in the literature to our knowledge. Because of their location, they are resistant to gross total resection and command careful consideration of adjuvant treatment. Here, we review the existing literature describing these cases, along with our own additional patient. Most patients (91.3%) with optic gangliogliomas presented with progressive visual disturbances, and the majority were male (69.6%), as with gangliogliomas in general. Ophthalmological evaluation is warranted in these patients, followed by neurological imaging (preferably MRI). Screening for neurofibromatosis type 1 (NF1) is essential, as NF1 patients represent a disproportionate number of optic ganglioglioma cases (13.0%). Gross total resection should be attempted only if vision is beyond salvage, as this can be curative. Otherwise, when serviceable vision remains, subtotal resection with adjuvant radiation should be carried out when feasible. Despite treatment, the prognosis remains mixed, with roughly one-third of patients progressing. (C) 2014 Elsevier Ltd. All rights reserved.
