Grey-white matter interface (G-WMI) displacement: a new sign in the computed tomographic diagnosis of subtle subdural haematomas.
Subtle and isodense subdural haematomas present difficult problems on computed tomography (CT). The diagnosis is based predominantly on secondary signs of mass effect. A new sign is described, based on the detection of medial displacement of the grey-white matter interface (G-WMI). The presence and validity of this sign was evaluated in 66 cases with surgically proven subdural haematomas (SDH).
