[A case of intraventricular meningioma manifesting akinetic mutism after complicated management of hydrocephalus].

A 26-year-old male with large intraventricular meningioma developed acute hydrocephalus postoperatively, which was difficult to manage. After a repeated course of dilated and slit-like ventricle, he gradually presented a disturbance of consciousness, which was recovered by the use of bromocriptine, suggesting akinetic mutism. At the chronic stage, he suffered from symptoms of hydrocephalus again.

Diagnosis of acute ischemic stroke based on time-to-peak and diffusion-weighted magnetic resonance imaging.

Rapid and accurate diagnosis of the hemodynamics of the brain is essential for the treatment of acute ischemic stroke. This study investigated whether time-to-peak and diffusion-weighted magnetic resonance (MR) imaging are useful for predicting the course of stroke. Fourteen patients with non-lacunar acute ischemic stroke underwent emergent MR imaging within 24 hours from the onset followed by cerebral angiography and xenon-enhanced computed tomography (CT).
