Exercise Induced Transient Neurological Deficit in a Patient with Cerebellar Developmental Venous Anomaly.

BACKGROUND The association of venous angiomas or developmental venous anomalies (DVA) with transient neurological deficit is rare. We present a rare case of a cerebellar developmental venous anomaly resulting in transient neurological deficits. CASE DESCRIPTION A 58-year-old man with recurrent left sided facial dysesthesia, hemiparesis, and mild difficulty ambulating after exercise. A similar episode was experienced six months earlier under the same circumstances. Computed tomographic (CT) scan demonstrated an ill-defined hyperdensity in the right cerebellar hemisphere. Cerebral angiography demonstrated a venous angioma that dilated with valsalva maneuver. CONCLUSION We report the first case of a cerebellar venous angioma causing exercise induced transient neurologically deficits. Limiting strenuous exercise may be needed to avoid symptom recurrence. Further research is warranted on the hemodynamic effects of intracranial DVA's.
