Neurologic and psychologic complications are usually related to drug toxicity, infections or symptoms induced by deterioration of renal allograft function. Metabolic encephalopathy, hypertensive encephalopathy, cerebrovascular events, and new-onset seizures have all been reported in organ-transplant recipients. Infections can be caused by listeria, cryptococcus, nocardia, aspergillus and mu...

Hypertensive encephalopathy rarely presents with predominant involvement of the brain stem and relative sparing of the supratentorial regions. We describe the MR imaging features in a patient with reversible brain stem hypertensive encephalopathy. Extensive hyperintensity was predominantly seen in brain stem regions on fluid-attenuated inversion-recovery and T2-weighted images. These lesions sh...

Computed tomographic (CT) scans were evaluated in 11 patients with acute hypertensive encephalopathy. Hypertensive encephalopathy is characterized by an acute, severe rise in blood pressure associated with headache, nausea, vomiting, altered mental status, and focal neurologic deficits, and rapid improvement after control of blood pressure. The systolic blood pressure range is 200-280 mm Hg; di...

Dural arteriovenous fistulae (DAVFs) in adults are generally regarded to be acquired lesions that may follow trauma, surgery, or thrombosis of a dural sinus (1, 2). Normal dural sinuses contain small arteriovenous anastomoses which do not appear to create any problem (3). In a setting of venous hypertension possibly in association with local angiogenic factors or congenital abnormalities of the...
