Calcified chronic subdural collection (armoured brain) is a known long-standing 
complication of shunt overdrainage. We report a young male who became 
symptomatic eleven years after a shunt surgery. Radiology showed bilateral 
calcified subdural collections. Drainage of these collections did not help, but 
shunt revision did. Patients with armoured brain syndrome who suddenly become 
symptomatic should possibly undergo shunt revision before the more extensive and 
morbid procedure of drilling the membranes.
