Posterior reversible encephalopathy syndrome (PRES) can cause rare, severe cerebellar swelling and obstructive hydrocephalus. Prompt recognition of atypical PRES imaging is crucial for effective patient management and preventing poor outcomes.
Area of Science:
- Neurology
- Radiology
- Neuroscience
Background:
- Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder characterized by vasogenic edema, typically in the parieto-occipital regions.
- PRES is associated with conditions like hypertensive emergencies, autoimmune disorders, and certain medications.
Observation:
- A rare case of PRES presented with severe cerebellar edema and acute obstructive hydrocephalus.
- This atypical presentation mimicked a mass lesion or infection on neuroimaging.
Findings:
- The patient's clinical presentation included headache, visual disturbances, seizures, and altered consciousness.
- Neuroimaging revealed significant cerebellar edema contributing to obstructive hydrocephalus.
Implications:
- Awareness of atypical PRES neuroimaging findings is critical for accurate diagnosis and timely management.
- Early identification and treatment of the underlying cause of PRES can lead to favorable outcomes and prevent serious complications.
