A case of primary post-traumatic intraventricular hemorrhage is presented. The patient, a 22 years-old man, after a mild head injury and a lucid interval lost consciousness and progressively developed symptoms of raised intracranial pressure. CT scanning, 24 hours later, revealed blood in the ventricles without concomitant brain contusion. The patient's condition improved dramatically after an external ventricular drainage.
We report a case of an aneurysm originated from a vermian branch of the superior cerebellar artery. The aneurysm located in the precerebellar space of the tegmentum was successfully clipped via a transoccipital transtentorial approach.
Spontaneous arterio-venous fistulae of the vertebral artery are rare. These lesions mainly affect the upper cervical area, and are usually asymptomatic, or may present as small, often pulsatile, cervical masses with vascular murmurs. The authors report on two cases in which the presumptive diagnosis, suggested by venous digital subtraction angiography, was then confirmed by selective angiography. In both cases an intravascular approach with detachable balloons and particulate substances was carried out, with good anatomical and functional results. Problems related to diagnosis, pathophysiology of symptoms, indications for treatment and embolization techniques are discussed.
In four cases with trigeminal neuralgia an intracranial neoplasm was detected. In the first two cases a meningioma of the cerebellopontine angle was producing symptomatic trigeminal neuralgia almost identical to the essential one. In the other two cases with a tumor in the gasserian ganglion area the facial pain was of a more atypical nature. In all four cases associated sensory trigeminal deficits were present. The causative factors which may produce symptomatic trigeminal neuralgia are especially discussed in this paper.
