There are bilateral asymmetrical thalamic, left basal ganglia and left side of midbrain lesions showing low signal intensity on T1WI high signal intensity on FLAIR and T2WI without surrounding perilesional oedema, causing mild shifting of midline structures to the right side.
The 3rd ventricle is compressed by the masses with subependymal oedema, indicating active hydrocephalus.
No enhancement following IV contrast.
No restricted diffusion.
Normal opacification of all dual venous sinuses.
