There is an extensive thickening of the basal subarachnoid cisterns with an intense enhancement, extending along the middle cerebral arteries to the Sylvian fissures, sellar and suprasellar regions as well as the cavernous sinuses with numerous conglomerate enhancing exudates and ring lesions (largest at the suprasellar region and right Sylvian fissure). Dilated 3rd, and lateral ventricles with mild interstitial periventricular oedema, indicating obstructive hydrocephalus.
Extensive nodular and ring-like enhancement along the surface of the cerebellar and cerebral hemispheres as well as the bulb and brainstem.
Mild dilatation of the 3rd and lateral ventricles suggesting associated obstructive hydrocephalus.
