Left Thalamus Arteriovenous Malformation Secondary to Radiation Therapy of Original Vermian Arteriovenous Malformation: Case Report
A 70-year-old gentleman with history of hypothyroidism, hyperlipidemia, hypertension, and right superior cerebellar aneurysm presented to the neurosurgery service in 2008 with vertigo. Diagnostic cerebral angiography performed that year demonstrated a vermian arteriovenous malformations (AVM). The patient underwent stereotactic proton beam radiosurgery, which resulted in a decrease in flow and size of the lesion, and the patient was lost to follow-up. Now at the age of 80, the patient presented with acute gait instability.

Clinical Reasoning: Corpus callosum lesion with multiple strokes
A 71-year-old woman with hypertension, diabetes, and recent stroke presented with acute left hemiparesis, which started 3.5 hours earlier but improved by the time of emergency department evaluation. Examination showed mild left-sided pronator drift and sensory extinction. Her history was significant for resection of a right frontoparietal meningioma for which she had received adjuvant radiation therapy 3 years previously.

Recurrent stroke in childhood cancer survivors
Conclusion: Survivors of childhood cancer, particularly those previously treated with high-dose cranial radiation, have a high risk of recurrent stroke for decades after a first stroke. Although these strokes are mostly occurring in young adulthood, hypertension, an established atherosclerotic risk factor, independently predicts recurrent stroke in this population.
