| Discussion | Developmental venous anomaly associated with unilateral dystrophic calcification of the basal ganglia and thalamus Background: DVA is the most common cerebral vascular abnormality (3%) and generally follows a benign clinical course. In rare cases, chronic venous hypertensive changes in the territory drained by a DVA may lead to dystrophic calcification of the drainage territory. This may be related to stenosis of the DVA or may be related to wall thickening and increasing resistance in the absence of frank stenosis. Clinical Presentation: DVAs are generally incidental findings and are only very rarely symptomatic. Key Diagnostic Feature: Unilateral calcification of the basal ganglia, without mass effect, associated with a developmental venous anomaly Differential Diagnoses: Prior unilateral injury such as infection or neoplasm (lymphoma, toxoplasmosis, neurocysticercosis, tuberculosis and other granulomatous diseases, HIV-related infection, chemo or radiotherapy) nonketotic hyperglycemic hemichorea-hemiballismus |
