Thin scalp haematoma overlying the left lambdoid suture. Contracoup right frontal and temporal intraparenchymal haemorrhages and trace adjacent extra-axial haemorrhage. A single locule of gas is seen within the left transverse sinus and there is hyperdensity of the left sigmoid sinus suspicious for acute thrombosis. There is subtle diastasis of the left lambdoid suture and small volume fluid within the left mastoid air cells.
