title: [Neuroglial heterotopia. Apropos of 8 cases with non-nasofrontal sites].
abstract: Neuroglial heterotopia, glioma, is an uncommon congenital nervous tissue tumor, usually found in a nasofrontal localization. About 60 cases with an atypical localization, usually in the pterygomaxillary fossa have been reported. We present 8 cases. Symptomatology followed CT-scan or MRI identified localization and was helpful in orienting diagnosis before biopsy. Exeresis was difficult, particularly in deep infratemporal localizations reaching the base of the skull. The main risk is recurrence. Different surgical approaches have been discussed and should be adapted to each case.
