Summary
Hypertensive encephalopathy can affect the cerebellum, causing swelling and dangerous hydrocephalus. Prompt treatment of high blood pressure and cerebrospinal fluid pressure is crucial for recovery.
Area of Science:
- Neurology
- Nephrology
- Critical Care Medicine
Background:
- Hypertension-induced encephalopathy typically affects the parietal and occipital lobes.
- Posterior fossa involvement, specifically cerebellar edema, is rarely reported.
Observation:
- Two cases of isolated cerebellar hemisphere edema occurred during hypertensive crises.
- Patients presented with decreased neurological status, malignant hypertension, and obstructive hydrocephalus.
Findings:
- Imaging revealed cerebellar edema, effacement of the fourth ventricle, and dilation of lateral and third ventricles.
- External ventricular drains and blood pressure control led to neurological recovery.
- Cerebellar edema resolved with blood pressure management, suggesting a breakdown of the blood-brain barrier.
Implications:
- This study highlights hypertensive encephalopathy as a potential cause of posterior fossa edema.
- Early recognition and management of severe hypertension are critical in preventing severe neurological outcomes.
- Cerebellar involvement in hypertensive encephalopathy expands the understanding of its pathophysiology.
