Armoured brain: A case of bilateral calcified chronic subdural haematoma complicating infantile hydrocephalus

Chronic Subdural haematoma is one of the late complications of shunting procedures. Calcified Chronic Subdural haematoma (CCSDH) which is very rare, follows untreated or asymptomatic Chronic subdural haematomas. When it occurs bilaterally it gives the typical appearance of an “armoured brain” also known as “Matrioska head”. The authors present a case of bilateral CCSDH found on follow-up CT brain scan 15 years after the shunt procedure. The parents had objected to surgical drainage at the time the initial diagnosis was made. The patient is neurologically stable with functional ventriculoperitoneal shunt. The discussion includes a review of relevant literature and treatment options
