The iso-mildly hyperdense (pre-contrast), homogeneously enhancing right cerebellopontine angle mass, favoured to be a meningioma, is unchanged in overall size, with perhaps slightly more convex margins. It demonstrates marginally increased surrounding vasogenic oedema. There is persisting stable 4th ventricular effacement and mass-effect on the right cerebellar hemisphere and cerebral peduncle and stable leftward cerebellar midline shift.
There is also mildly increased obstructive hydrocephalus involving the 3rd and lateral ventricles since the previous imaging.
A small amount of high density is present within the dependent part of the 4th ventricle, not convincing for blood, similar to the previous CT.
No intracranial haemorrhage or extra-axial collection. No evidence of acute infarction. No other new findings since the MRI.
