[Cerebellar infarct in hypertensive crisis]

Area of Science:

• Neurology
• Vascular Neurology
• Neuroanatomy

Background:

• Hypertensive crisis can lead to severe neurological complications.
• Cerebral edema and brainstem herniation are known risks in severe hypertension.
• Cerebellar infarction is a serious outcome of compromised blood flow to the cerebellum.

Observation:

• A patient experienced cerebellar infarction during a severe hypertensive crisis.
• Cerebral edema caused brainstem structures to shift into the foramen magnum.
• This shift compressed the right inferior posterior cerebellar artery.

Findings:

• The cerebellar infarction resulted from compression of the inferior posterior cerebellar artery.
• A rare anatomical variant in the artery's course contributed significantly to the pathogenesis.
• The compression occurred at the great occipital foramen.

Implications:

• Highlights an unusual mechanism for cerebellar infarction in hypertensive crisis.
• Emphasizes the role of neurovascular anatomical variations in disease.
• Suggests the need for considering anatomical anomalies in managing hypertensive emergencies.
