ABSTRACT
Background: Extrapontine myelinolysis is part of the osmotic demyelination
syndrome, being an acute non-inflammatory demyelinating disease caused by hyperosmotic
stress that injures oligodendrocytes and causes myelin loss in regions of the
central nervous system other than the pons of the brain stem. Primarily caused by a
rapid sodium correction in patients with hyponatremia, in pregnant women its most
frequent association is with hyperemesis gravidarum.
Clinical case: A 32-year-old indigenous woman was referred to a university hospital
of high complexity, in Bogotá, from a territory of the Colombian Amazon, within
the framework of a new health care model, with a 15-week pregnancy, who had a
convulsive episode, aphasia and oral automatism, and a recent history of hyperemesis
gravidarum. Another history of hyperemesis and hyponatremia a month ago. Initially,
eclampsia and neuroinfection were suspected, a rapid correction of sodium, anticonvulsant,
remission and management in the intensive care unit was performed. MRI was
compatible with extrapontin myelinolysis. After a month she returned to the territory
of origin for rehabilitation. She had a home delivery at 38.3 weeks and went to the
hospital for placental delivery.
Conclusion: Extrapontin myelinolysis should be considered in the differential diagnosis
between pregnancy with acute neurological symptoms conditions and a history
of hyperemesis or hyponatremia. In case of a repeated history of acute hyponatremia
in pregnant women with hyperemesis, chronicity should be considered. It is recommended
to integrate university hospitals to rural territories to optimize the diagnosis
and management of this type of cases.
