| pubmed-article:1780611 | pubmed:abstractText | A 72-year-old man presented with an apparent frontal syndrome. He also had bilateral trigeminal neuralgia, a pyramidal syndrome of all 4 limbs, balance disturbances, a horizontal nystagmus when looking to the left and a right velopalatine paralysis. CT scan with contrast showed a hyperdense rounded lesion in the left cerebello-pontine angle. Cerebral angiography showed this to be a large aneurysm of the end of the vertebral arteries. The patient died suddenly. Autopsy confirmed the site and presence of the aneurysm. Balance disturbances, the pyramidal syndrome and velopalatine paralysis could all be explained by brain stem compression and the bilateral nature of the trigeminal neuralgia by compression of the trigemino-thalamic tract. The apparent frontal syndrome, the authors suggest could have resulted from subacute raised intracranial pressure. | lld:pubmed |
