Patchy subcortical and cortical based T2/FLAIR high signal regions at the posterior aspects of the frontal lobes and the convexities of the parietal and occipital lobes, corresponding to regions of diffusion restriction. Associated susceptibility artefact within the largest of the cortical based T2 high signal regions at the right occipital lobe suggestive of haemorrhagic transformation.
Filling defect within the superior sagittal sinus extending into the right transverse sinus and sagittal sinus to the level of the jugular bulb. Left transverse sinus is nondominant. Marked pachymeningeal enhancement throughout the brain. Leptomeningeal enhancement is noted at the convexities of the posterior frontal lobes, the parietal and occipital lobes. No discrete extra-axial collections identified.
Linear susceptibility artefact is also noted at the left occipital lobe - probably sulcal. Downward transtentorial or tonsillar herniation with complete effacement of suprasellar cistern, no hydrocephalus.
