Hypertensive encephalopathy is an acute neurological syndrome caused by a sudden increase of systemic blood pressure (1, 2). The imaging abnormalities are predominant in the parieto-occipital subcortical white matter. The clinical and radiological abnormalities are reversible after antihypertensive treatment (3). Therefore, hypertensive encephalopathy has been called posterior reversible enceph...

Neurogenically caused cardiac arrhythmias and their correlation to lesions within the central nervous system were examined prospectively in 54 patients with spontaneous intracerebral hemorrhage. All patients were examined neurologically daily for 3 weeks, with special attention given to signs of brainstem compression resulting from transtentorial herniation. Electrocardiograms were continuously...

Fifteen vascular malformations, including six supratentorial arteriovenous malformations (AVMs), three venous malformations, and six brainstem vascular malformations, were examined on 0.5 T magnetic resonance (MR) and GE 9800 and 8800 computed tomographic (CT) scanners. All the malformations were shown by MR, and the arterial and venous drainage of AVMs was precisely delineated. Hematoma was al...

BACKGROUND Horizontal gaze palsy with progressive scoliosis (HGPPS) is an autosomal recessive disorder caused by mutations in the ROBO3 gene, resulting in a critical absence of crossing fibers in the brainstem. CASE PRESENTATION We present a patient with ipsilateral hemiparesis caused by putaminal hemorrhage who had a history of horizontal gaze paralysis and scoliosis since childhood. Diffusi...

BACKGROUND Tonic inward and downward deviation of the eyes ("peering at the tip of the nose") is regarded as a unique feature of thalamic hemorrhage, but the mechanisms of this ocular finding remain obscure. OBJECTIVES To describe 4 patients who showed tonic inward and downward deviation of the eyes from brainstem or thalamic lesions and to discuss the possible mechanisms involved. DESIGN C...

Spontaneous vestibular syndrome in mice, characterized clinically by head tilt, circling or rolling, can be caused by otitis media, arteritis or central nervous system lesions. Postmortem examination of eleven non-inbred Swiss mice submitted for necropsy due to acute onset of vestibular signs revealed lesions consistent with brainstem infarction. The lesions were characterized by unilateral, we...

A 30-year-old man was intubated after sudden severe headache, loss of consciousness, and apnea. CT showed acute hemorrhage in the posterior fossa, brainstem compression, and intraventricular extension with early obstructive hydrocephalus (figure 1A). MRI showed a large heterogeneously enhancing extra-axial tumor extending from the cerebellopontine angle to the foramen magnum (figure 1, B and C)...

BACKGROUND AND PURPOSE Validation of the Boston criteria for the in vivo diagnosis of cerebral amyloid angiopathy (CAA) is challenging, because noninvasive diagnostic tests do not exist. Hereditary cerebral hemorrhage with amyloidosis-Dutch type is an accepted monogenetic model of CAA and diagnosis can be made with certainty based on DNA analysis. The aim of this study was to analyze and refine...
