RESUMO
The vasogenic edema in structures of posterior fossa secondary to elevated hydrostatic pressure can cause obstructive hydrocephalus, a condition called "reversible obstructive hydrocephalus from hypertensive encephalopathy." A case of a 27-year-old woman with arterial hypertension and sign of raised intracranial pressure is reported. Her radiologic studies have showed vasogenic cerebellar edema without structural lesion. This edema leads to obstruction of the cerebral aqueduct. We discuss the clinical and therapeutic aspects of this condition. In this clinical situation, the accurate control of blood pressure is themain goal on medical care, and the need of permanent ventricular shunt is quite infrequent.
O edema vasogênico secundário a elevação da pressão hidrostática capilar pode causar hidrocefalia obstrutiva, a chamada Hidrocefalia Obstrutiva Reversível secundária a Encefalopatia Hipertensiva. Nós apresentamos umcaso de umamulher de 27 anos com hipertensão arterial e sinais de hipertensão intracraniana. Sua investigação radiológica evidenciou sinais de edema vasogênico cerebelar bilateral sem lesão estrutural, determinando obstrução do aqueduto cerebral Nós discutimos os aspectos clínicos e terapêuticos deste caso. Nesta condição, o adequado controle da pressão arterial é a principal medida terapêutica, sendo a necessidade de derivação liquórica permanente infrequente.

Reversible posterior leukoencephalopathy syndrome (RPLE) is an increasingly recognised disorder, most commonly associated with malignant hypertension, toxaemia of pregnancy or the use of immunosuppressive agents. Two cases of RPLE syndrome occurring in the setting of accelerated hypertension and eclampsia are described. Both patients had seizures, altered sensorium and typical findings on neuroimaging. They had complete clinical and radiological recovery. The clinical course, pathophysiology and neuroimaging features of RPLE syndrome are discussed.
