The syndrome of reversible posterior leukoencephalopathy syndrome(RPLS) is characterized clinically by acute neurologic signs such as headache, vomiting, confusion, seizures, and visual abnormalities. Radiologically, abnormalities consistent with reversible white matter edema in the occipital and parietal lobes are characteristic. RPLS has often been associated with various systemic disorders, such as hypertensive encephalopathy, eclampsia, and the use of intravenous or intrathecal immunosuppressive drugs. We report a case of RPLS that occurred after intravenous steroid pulse therapy and treatment with oral cyclophosphamide in a child with nephrotic syndrome, and we emphasize the importance of early recognition of RPLS in the treatment of nephrotic syndrome and appropriate management to prevent permanent neurologic disability.

Hypertensive brainstem encephalopathy (HBE) is a variant of hypertensive encephalopathy characterized by brainstem and cerebellar involvement. Simultaneous supratentorial involvement in HBE is rarely reported as a vasogenic edema in subcortex and/or periventricular white matter. A 36-year-old woman visited hospital due to headache lasting 7 days before admission. Initial blood pressure was 270/170mmHg. T2-weighted and fluid-attenuated inversion recovery magnetic resonance imaging revealed multifocal high signal intensity lesions in upper medulla, pons, midbrain and cerebellar hemisphere. Especially, atypical periventricular lesions were shown as perpendicular fingers to the lateral ventricle like multiple sclerosis. Her clinical symptoms and radiological lesions were subsided with lowering blood pressure. We herein report a HBE with unusual supratentorial involvement mimicking multiple sclerosis.

Reversible posterior leukonecephalopathy syndrome RPLS), a neurologie disorder associated with evidence of posterior cerebral edema on neuroimaging studies, has been described in both adults and children. Conditions predisposing to RPLS include malignant hypertension, renal dysfunction, toxemia of pregnancy, interferon therapy, and the use of immunosuppressive agents. When associated with acute hypertension, RPLS typically occurs concurrently with the fulminant clinical syndrome of hypertensive encephalopathy We describe occipital lobe seizures, in the setting of only moderate elevations of blood pressure, as the major clinical manifestation of RPLS.

Reversible posterior leukoencephalopathy with hypertension is characterized by an acute and severe rise in blood pressure with headache, altered mental status, cortical visual disturbance, seizure and transient edematous changes in neuroimaging. The most common abnormality in neuroimaging is presumed edema involving the cortical and subcortical white matter predominant in the posterior region of the cerebral hemisphere and rarely the cerebellum and the brain stem, but not in the spinal cord. We experienced a case of 10-year-old girl with hypertensive encephalopathy involving the brainstem and the spinal cord.

Hypertensive encephalopathy is a medical disorder, which occurs with sudden increase of blood pressure (BP). The MRI findings of hypertensive encephalopathy are diffuse hyperintensity on T2-weighted images, predominantly within the cortex and subcortical white matter of the parieto-occipital lobe. The brainstem is rarely involved. Diffusion-weighted images do not show any abnormalities. We report two patients with hypertensive encephalopathy whose MRI showed exclusive brainstem involvement. They improved rapidly after BP control.
