We present five cases of hypertensive encephalopathy in children, three with MR imaging findings and two with CT findings alone. One of the five patients had MR perfusion imaging, which showed perfusion abnormalities that support the concept of vasodilation as the major contributor to the syndrome. Hypertensive encephalopathy is rarely reported in children, and its true prevalence may be undere...

BACKGROUND Hypertensive encephalopathy is an uncommon neurological syndrome in children, usually with reversible clinical and neuroimaging findings. Little is known about the precipitating factors, clinical presentations, neuroimaging findings and outcomes of childhood hypertensive encephalopathy in Taiwan. METHODS To characterize this syndrome, we retrospectively analyzed 12 children with hy...

Post-infectious acute glomerulonephritis with hypertensive encephalopathy is characterized by episodic hypertension with headache, vomiting, and hematuria. The association between hypertensive encephalopathy and cortical blindness in children with acute glomerulonephritis is extremely rare. We report the case of a 10-year-old boy with acute glomerulonephritis who presented with gross hematuria,...

Pheochromocytoma is a rare cause of hypertension in children. Hypertension is one of the common reasons of posterior reversible encephalopathy. Intracerebral hemorrhage is a serious and unexpected complication of hypertensive encephalopathy due to pheochromocytoma, and very rarely seen in the childhood. Intracerebral hemorrhages should be searched if there are hypertensive reversible signal cha...

Posterior reversible encephalopathy syndrome (PRES) is characterized by acute onset of headache, nausea, focal neurological deficits or seizures along with radiological findings of white matter defects in the parietal and occipital lobes. Causes of PRES include uremia, hypertensive encephalopathy, eclampsia and immunosuppressive medications. Usually, the treatment of choice involves correcting ...

MD Mofid Children Hospital Email:[email protected] Objective Hypertension is called the silent killer and vital organs such as the brain, eyes, kidneys and the heart are the targets. Seizure, central nervous system (CNS) hemorrhage, and cerebrovascular accident (CVA), blindness and heart attacks are the end points. The prevalence of hypertension in ch...

Brain edema in patients with hypertensive encephalopathy frequently affects the parietooccipital white matter. Hypertensive encephalopathy is thus included as a differential diagnosis in reversible posterior leukoencephalopathy syndrome. Diffuse white matter involvement rarely occurs. We report a 41-year old woman with hypertensive encephalopathy with diffuse and non-enhancing white matter hype...

PURPOSE Hypertensive encephalopathy, a complex of cerebral disorders, including headache, seizures, visual disturbances, and other neurologic manifestations, is associated with a variety of conditions in which blood pressure rises acutely. It has been ascribed to either exuberant vasospasm with ischemia/infarction or breakthrough of autoregulation with interstitial edema. Diffusion-weighted MR ...

Hypertensive encephalopathy usually involves the posterior supratentorium, with uncommon involvement of the brainstem. We present a case of acute hypertensive encephalopathy of the brainstem diagnosed by means of CT. The brainstem was markedly hypodense, with no evidence of typical concomitant parieto-occipital involvement. The patient's symptoms and imaging findings improved after hypertension...
