Posterior reversible encephalopathy syndrome complicating postpartum eclampsia in a Nigerian: case report

This is a case of posterior reversible encephalopathy syndrome (PRES) associated with postpartum eclampsia in a primiparous Nigerian.

A 20-year-old primiparous woman presented to the emergency unit of the department of obstetrics and gynaecology of our hospital with symptoms and signs consistent with postpartum eclampsia. While being managed for this, she developed weakness of the left limbs with associated altered sensorium. Significant findings on physical examination were hypertension, left-sided hemiparesis and cortical blindness. She had a computed tomographic (CT) scan of the brain which showed features consistent with posterior reversible encephalopathy syndrome. She was given full supportive care with control of her blood pressure and she made a significant improvement. She was discharged home about 3 weeks after admission with improvement in clinical condition and is currently being followed up in our neurology clinic.

PRES complicating eclampsia is a clinicoradiological diagnosis. In most cases neurological symptoms improve with good supportive care and adequate treatment of the underlying condition as was the case in this patient. However permanent neurological sequelae can result from delayed diagnosis and treatment; therefore a high index of suspicion, early diagnosis and treatment are essential.
