Eclampsia can cause widespread cerebral edema in women, impacting neurological function. Imaging reveals edema patterns correlating with clinical symptoms and outcomes, highlighting the severity of this condition.

Area of Science:

  • Neurology
  • Obstetrics
  • Radiology

Background:

  • Eclampsia is a severe complication of pregnancy characterized by seizures.
  • Cerebral edema can occur in eclampsia, leading to significant neurological deficits.
  • Understanding the imaging findings of cerebral edema in eclampsia is crucial for patient management.

Purpose of the Study:

  • To describe and correlate clinical findings with neuroimaging results in women with eclampsia and cerebral edema.
  • To investigate the relationship between clinical presentation and radiological findings in eclamptic patients with brain edema.

Main Methods:

  • A descriptive study of 10 women diagnosed with eclampsia and symptomatic cerebral edema.
  • Clinical data and findings from computed tomography (CT) and magnetic resonance imaging (MRI) scans were analyzed.

  • Patient data were collected over a 13-year period at a single tertiary care hospital.
  • Main Results:

    • Symptomatic cerebral edema occurred in approximately 6% of eclamptic women.
    • Three women experienced symptoms after severe hypertension, with radiographic evidence of impending herniation; one died.
    • The remaining seven women presented with persistent central nervous system symptoms, including altered consciousness and visual disturbances, with edema often at the gray-white matter junction or unilaterally.

    Conclusions:

    • Symptomatic cerebral edema in eclampsia likely stems from a spectrum of central nervous system lesions.
    • The edema may involve both cytotoxic (ischemic) and vasogenic (hypertension-related) components.
    • Neuroimaging findings correlate with clinical severity and can indicate poor prognosis.
