Multiple areas of intra-axial haemorrhage in both frontal lobes at the convexity. A small subarachnoid haemorrhage is seen along the interhemispheric fissure.
The superior sagittal sinus anteriorly and in its mid portion to approximately 10cm above torcula is hyperdense on non-enhanced imaging and shows no enhancement post-contrast in the venogram phase supporting a large acute thrombosis.
Some cortical veins are also hyperenhancing suggesting early thrombosis.
Conclusion: Large acute thrombosis of the superior sagittal sinus with associated intraparenchymal and subarachnoid haemorrhage.
