What are the findings?
Biilateral subacute subdural haematomas with no evidence of midline shift. Small lateral ventricles, raising the possibility of mass effect.
What are the CT features of subdural haematomas?
Crescent-shaped homogeneously hyperdense extra-axial collection that spreads diffusely over the affected hemisphere in the acute phase. In the subacute phase the density approaches that of the adjacent cortex, making visualisation difficult. In this phase the secondary signs to look for are: -apparent thickening of the cortex -mass effect including sulcal distortion and midline shift -CSF filled sulci do not reach the skull but instead fade out into the surrounding subdural space
Bilateral subacute subdural haematomas, larger on the left, with no evidence of midline shift. The lateral ventricles appear small, suggesting a degree of mass effect. There is no intracranial blood. Normal gray-white matter differentiation.
