Abstract:
This index case report describes a patient who presented with unilateral hyperkinetic choreiform movements of the left neck, arm, and leg caused by right-sided putamen and caudate calcification as the product of an underlying developmental venous anomaly (DVA). No underlying metabolic disorder or other calcium-related disorder was present. Calcification of the putamen and caudate has been described in relation to an underlying DVA which results in localized venous hypertension and other changes, and tends to spare the anterior limb of the internal capsule. This resulting unilateral choreiform movement disorder has not been described in the literature and represents the need for greater recognition of this entity in the differential for lateralizing hyperkinetic disorders.
