Head trauma and brain tumours revisited.

The authors report a case of an anaplastic astrocytoma which on magnetic resonance imaging and direct visualisation was continuous with an area of gliosis in the left frontal lobe. This gliosis was secondary to a head injury received 19 years earlier that required evacuation of an intracerebral haematoma. This case largely meets the accepted criteria for brain tumour associated with head trauma. Copyright 2000 Harcourt Publishers Ltd.
