| Popis: | Aneurysms of the posterior fossa represent approximately 8 per cent of all intracranial aneurysms. These aneurysms may rupture to produce the familiar picture of subarachnoid hemorrhage, may be asymptomatic or may enlarge without rupturing to produce a multitude of neurologic symptoms. The diffuse ectasias of the vertebro-basilar system rarely rupture but may be indistinguishable clinically from a large aneurysm.Posterior fossa aneurysms or ectasias may mimic cerebellopontine angle tumor, especially acoustic neuroma or pontine glioma and "posterior fossa mass." Less frequently, such an aneurysm or ectasia may precipitate a psychosis, trigeminal or glossopharyngeal neuralgia, or a spinal cord lesion.The most characteristic clinical picture of a patient with a large unruptured posterior fossa aneurysm or ectasia is a prolonged, episodic and progressive course of cerebellar, pontine or medullary symptoms and signs. Headaches, disturbances of equilibrium, nystagmus, lower cranial nerve involvement and pyramid... |
