A large region of wedge-shaped hypodensity blurring the grey-white matter differentiation in the right temporoparietal region contains a moderate volume of parenchymal haemorrhage, which measures 5.8 x 3.7 x 2.7 cm. The right transverse sinus is hyperdense and shows thrombus in the venogram study. There is moderate mass effect, with effacement of the occipital horn of the right lateral ventricle, effacement of right-sided sulci and subfalcine herniation to the left of up to 5 mm at the septum pellucidum. No other regions of haemorrhage or loss of grey-white matter association. No hydrocephalus.
Filling defect in the right transverse sinus, extending to the sigmoid sinus, jugular bulb and upper right internal jugular vein. The superior sagittal sinus, straight sinus and left transverse sinus opacifies normally. The deep cerebral veins also opacified normally.
No skull fracture. The paranasal sinuses and mastoid air cells are clear.
Conclusion: Deep venous sinus thrombosis involving the right transverse and sigmoid sinuses, extending to the jugular bulb and a right internal jugular vein. Associated venous infarct and haemorrhage.
