Reversible posterior encephalopathy syndrome associated with late onset postpartum eclampsia: A case report

Malignant PRES and RCVS after brain surgery in the early postpartum period

The management of women with brain tumors in the early post-partum period may be demanding as the patho-physiological changes that occur during pregnancy may also manifest in the early post-partum period. The aim of our paper is to report a case of late-onset post-partum pre-eclampsia after brain tumor surgery, complicated by posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS). Hemicraniectomy and intensive care management were necessary to obtain a favorable neurological outcome. The inherent literature on the subject is also analyzed through a systematic research. This is the first case of supratentorial decompressive hemicraniectomy in post-partum PRES, while there has been only one other case of posterior fossa decompression described in this cohort of patients. PRES and RCVS can complicate the neurosurgical management of women in the postpartum period. A careful evaluation of the clinical presentation is necessary as in some particular cases an aggressive medical and surgical treatment is required to obtain a favorable outcome.

Post-partum posterior reversible encephalopathy syndrome requiring decompressive craniectomy: case report and review of the literature

Posterior reversible encephalopathy syndrome (PRES) is an uncommon but potentially devastating syndrome if not recognized and treated appropriately. As the name implies, recognition of the condition and proper management may reverse the clinical and radiological findings. However, diagnosis is not always straightforward. We present the case of a 24-year-old female who was 4 days post-partum and presented with headache, neck pain, and new-onset seizures. She had undergone epidural anesthesia during labor, and initial imaging was suggestive of intracranial hypotension versus pachymeningitis. Despite initial conservative therapy including anti-epileptic drugs, magnesium therapy, empiric antibiotics, and Trendelenburg positioning, the patient continued to deteriorate. Follow-up imaging was suggestive of PRES with signs of intracranial hypertension. The patient underwent a decompressive suboccipital craniectomy for refractory and severe PRES and later fully recovered. This case highlights the sometimes difficult diagnosis of PRES, possible association with pregnancy, eclampsia/preeclampsia and/or cerebrospinal fluid drainage, and the rare but life-saving need for decompression in severe cases.

Transient cortical blindness in posterior reversible encephalopathy syndrome after postpartum eclampsia

Posterior reversible encephalopathy syndrome (PRES) is a clinical condition that can cause different ophthalmological and neurological symptoms. Preeclampsia toxemia or eclampsia is one of the leading causes of PRES. Herein, we present a study of a 35-year old woman who gave birth to healthy twins at 35 weeks of gestation by cesarean section because of threatened preterm delivery. On the 1^st postoperative day, the woman developed a severe headache, arterial hypertension, tachycardia, generalized tonic-clonic seizures, and loss of consciousness that persisted for about 2 min. A provisional diagnosis of eclampsia was made, and the woman was then quickly transferred to the intensive care unit where she was treated with antihypertensive therapy, magnesium sulphate, and diazepam. Following stabilization of the general condition, the patient noticed sudden bilateral blindness. An ophthalmological examination revealed significant bilateral loss of vision at the level of insecured light perception, normal pupillary responses to a light stimulus, and normal fundus findings. On this basis, an ophthalmologist made the diagnosis to cortical blindness. Radiographic analysis showed an edematous change in the occipital and parietal brain regions, thus suggesting a diagnosis of PRES. In conclusion, cortical blindness is a clinically striking ophthalmic disorder that may occur in PRES associated with postpartum eclampsia.
