title: Chronic extradural haematoma with delayed expansion.
abstract: A 35-year-old man became symptomatic 26 months after a head injury. CT showed an occipital-suboccipital chronic extradural haematoma (EDH). A surrounding membrane, with neovascularisation, was evident, both, on CT and at surgery. This unusually long interval between trauma and onset of symptoms suggests that delayed expansion of a chronic EDH should be kept in mind if planning conservative management. An EDH can be considered 'cured' only after disappearance of the membrane and haematoma on CT.
