title: Overlapping features of eclampsia and postpartum angiopathy.
abstract: BACKGROUND
  Postpartum cerebral angiopathy (PPA) is considered one of a diverse group of rare conditions termed "reversible cerebral vasoconstriction syndromes". Existing literature suggest considerable overlap in the manifestations of eclampsia and PPA.
  
  
  METHODS
  Retrospective case series review of PPA and eclampsia from a single neurosciences intensive care unit patient log identified over a consecutive 18-month period. A MEDLINE search (using OVID) of the English literature from 1950 through October 2008 was also performed.
  
  
  RESULTS
  Four patients who meet the obstetrical criteria for eclampsia and four patients whose clinical and radiographic features were consistent with PPA were identified. Twenty-eight patients with PPA were identified from the literature and showed significant clinical and radiographic overlap without cohort.
  
  
  CONCLUSIONS
  Given the overlapping clinical, laboratory, and radiographical features of eclampsia and PPA, it is probable they share a similar underlying pathophysiological mechanism and represent different clinical expressions of the same pregnancy-related disorder. The obstetrical definition of eclampsia may be to strict when applied in the neurosciences intensive care unit.
