Summary
Reversible posterior encephalopathy syndrome (PRES) is a rare postoperative complication. This case highlights PRES following microvascular decompression, emphasizing prompt diagnosis and management for improved patient outcomes.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Reversible posterior encephalopathy syndrome (PRES) is a neurological condition characterized by cerebral vascular dysregulation and blood-brain barrier disruption.
- PRES presents with symptoms like seizures, headaches, altered mental status, and visual disturbances, and is typically reversible with prompt treatment.
- While uncommon postoperatively, PRES is most frequently observed after posterior fossa surgeries in neurosurgery.
