Primary aortic sarcoma is a rare condition that is frequently associated with distal embolization. In addition, growth characteristics of primary aortic sarcoma lead to the narrowing of the involved aortic lumen. A 72-year-old Korean male with primary aortic sarcoma showed progressive unexplained blood pressure elevation that didn't improve with additional antihypertensive drug therapy. Because...

Hypertensive encephalopathy was induced in the rat by clipping one renal artery and contralateral nephrectomy. The possible changes of vascular permeability of the cerebral blood capillaries and venules were investigated by using ferritin as a tracer. The uninephrectomized rats served as controls. In controls, ferritin was never seen in the basement membranes, within plasmalemmal vesicles on th...

An 80-year-old hypertensive woman developed right hemiplegia and died 24 hours after admission. Neuropathologic examination revealed multiple cerebral infarcts of various ages and diffuse subcortical arteriosclerotic encephalopathy. Clusters of asymptomatic "expanding" lacunes, due to dilatation of the perivascular spaces, were found in both dentate nuclei. These cavities, which presented as sp...

Allgrove syndrome or triple-Asyndrome is a rare familial multisystem autosomal recessive disorder. It is characterised by triad of alacrima, achalasia and adrenal insufficiency due to adrenocorticotropin hormone (ACTH) resistance. If it is associated with autonomic dysfunction, it is termed as 4-Asyndrome. This syndrome is caused by a mutation in the Achalasia - Addisonism - Alacrima (AAAS) gen...

Presented here is a 36-year-old male with arterial hypertension who developed brainstem edema and intracranial hemorrhage. Magnetic resonance scan revealed diffuse brainstem hyperintensity in T2-weighted and fluid-attenuated inversion-recovery images, with an increase in apparent diffusion coefficient values. After a reduction in blood pressure, rapid resolution of the brainstem edema was obser...

It is important to have a good understanding of the pat­hogenetic diagnosis and treatment features severe complication with high mortality – hypertensive encepha­lopathy (HE) because amount people suffering from chronic arterial hypertension constantly increa­sing. Thus, this article briefly reviews mechanism cerebral blood flow autoregulation, HE pathophysiology, main aspects treatment. An epi...

Posterior reversible encephalopathy syndrome (PRES) is associated with various clinical manifestations such as headache, blurred vision, confusion and tonic-clonic convulsion. Some of the predisposing factors for PRES include hypertensive encephalopathy, preeclampsia and eclampsia, lupus erythematosus, thrombotic thrombocytopenic purpura and long-term use of immunosuppressive drugs. This condit...
