The superior sagittal sinus (SSS) appears significantly attenuated with thrombosis of its superior portion demonstrating intermediate T2 and FLAIR signal intensity. MR venography confirmed thrombosis of the SSS with lost signal.
Evidence of high posterior parietal and frontal subarachnoid haemorrhage smearing the cortical sulci. Thrombosis and distension of the related cortical veins are noted as well.
Left high posterior parietal acute infarction with high diffusion-weighted image (DWI) and low ADC signal.
Normal ventricular system. Normal sellar and parasellar region. Normal posterior fossa.
Normal MR angiography of the cerebral arteries.
