title: [Oculomotor nerve schwannoma in a child: Case report and literature review].
abstract: An isolated schwannoma of the oculomotor nerve is rare in children without an associated neurofibromatosis. A 13-year-old girl, with a previous medical history of migraine, was admitted for disabling ophthalmic migraine with oblique diplopia. The clinical examination showed a right incomplete ophthalmoplegia with reduced ipsilateral visual acuity (8/10). There was no particular skin reaction. The MRI revealed a right (isosignal-T1 and isosignal-T2) nodular schwannoma located within the cisternal segment of the oculomotor nerve. The angio-CT performed later confirmed the absence of any vascular malformation. The treatment consisted of analgesics and corticotherapy, with complete regression of symptoms three weeks later and a normal MRI follow-up. Therefore, radiosurgery was not performed.
