"Pseudotumoral" cystic cerebellar infarction with slow evolution

Area of Science:

• Neurology
• Neurosurgery
• Cerebrovascular Disease

Background:

• Cerebellar infarction is typically an acute event.
• Slowly evolving cystic forms of cerebellar infarction are not well-recognized.
• Cerebrovascular events require timely diagnosis and management.

Observation:

• A 63-year-old female presented with sudden-onset cerebellovestibular symptoms and posterior headaches.
• Neurological condition progressively worsened over 5 months.
• Imaging revealed a cystic infarction of the cerebellar lobe with hydrocephalus.

Findings:

• The case suggests a slowly evolving, cystic cerebellar infarction.
• Literature review identified two similar cases.
• This presentation indicates a distinct subtype of cerebellar infarction.

Implications:

• Recognition of this slowly evolving cystic cerebellar infarction subtype is crucial.
• A direct surgical approach may be warranted for optimal patient outcomes.
• Further research into the pathophysiology and treatment of cystic cerebellar infarction is needed.
