ABSTRACT
Se describen los Síndromes de disfunción de nervios craneales V- VII-VIII-IX-X y XII y la evolución histórica que ha tenido su tratamiento quirúrgico. Se discute la posible etiología, fundamento de la terapia quirúrgica. Se presenta la principal experiencia internacional, la del autor y los resultados. Se enfatiza la indicación en afecciones de tratamiento neuro quirúrgico poco común como el tortícolis espasmódico y ciertos casos de hipertensión arterial esencial. Se destaca la necesidad de alto nivel en técnica microquirúrgica.

Chondroid chordoma is a variant of chordoma; it may rarely involve the petrous temporal bone and has a high propensity for recurrence. Chordoma rarely metastasizes but it is, nevertheless, associated with a poor outcome. We report a rare case of chondroid chordoma with extensive recurrence and pulmonary metastases.

Carotid cavernous dural arteriovenous fistula (DAVF) usually presents with conjunctival injection, proptosis, loss of visual acuity and ophthalmoplegia. There have been some carotid cavernous DAVF case reports presenting with isolated oculomotor, abducens and trochlear nerve palsy. We experienced a patient presenting with bilateral abducens nerve palsy and no other ocular signs who was diagnosed as carotid cavernous DAVF after conventional angiography. According to this case, carotid cavernous DAVF should be considered in the differential diagnosis of isolated bilateral abducens nerve palsy, in which case conventional angiography may be helpful in diagnosis.

The clinical course of cryptococcal meningitis in AIDS shows some important differences from the features of the illness in non-AIDS patients. Complications such as raised intracranial pressure and visual impairment that are recognised in non-AIDS patients may be less frequent in those with AIDS. Persistent intracranial hypertension should be managed actively to prevent visual impairment. In AIDS patients; in whom ventriculo-peritoneal shunts carry additional risks; acetazolamide can be used successfully to lower the CSF pressure and prevent visual loss
