Posterior leukoencephalopathy syndrome (PRES) can cause seizures and vision loss in eclamptic and non-eclamptic patients. Prompt diagnosis using MRI is crucial for excellent symptom resolution.

Area of Science:

  • Neurology
  • Radiology

Background:

  • Posterior leukoencephalopathy syndrome (PRES) is a neurological condition characterized by headache, seizures, visual disturbances, and altered sensorium.
  • PRES predominantly involves vasogenic edema in the occipital and posterior parietal white matter.
  • It can be triggered by conditions like preeclampsia-eclampsia and occur postpartum.

Observation:

  • Two cases are presented: one eclamptic and one noneclamptic patient.
  • Both patients exhibited symptoms consistent with PRES.

Findings:

  • PRES is characterized by vasogenic edema in the brain's posterior white matter.
  • Distinguishing PRES from cerebral ischemia requires advanced MRI techniques, including diffusion-weighted imaging.

Implications:

  • Early identification and management of PRES are essential.
  • The prognosis for PRES is generally favorable, with potential for complete symptom resolution.
