Developmental venous anomaly: a rare cause of cerebellar ataxia

The most common causes of acute cerebellar ataxia are vascular disorders resulting in cerebellar ischaemia or haemorrhage. Most cerebellar haemorrhages are midline and therefore present with gait ataxia, truncal ataxia, dysmetria of lower extremities, saccadic intrusions and vertigo. Symptoms for cerebellar hemisphere lesions include dysdiadochokinesis, dysmetria of upper extremities, limb ataxia, intention tremor and scanning speech. Chronic progressive ataxias are most commonly degenerative and frequently hereditary in origin; they account for half the cases of adult onset ataxia.1 Developmental venous anomalies are commonly encountered congenital anatomical variations of the cerebral vasculature—a malformation of …
