Abstract
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.
