There is a well-defined intraventricular lesion centred in the left trigone/occipital horn, which is hypointense on T1 and hyperintense on T2 and demonstrates slight diffusion restriction. There is moderately extensive surrounding oedema in the left periventricular parieto-occipital deep white matter. Intense but heterogeneous enhancement and the lesion shows contiguous enhancement with the choroid plexus best appreciated on the anterior and inferior aspect of the lesions however this may represent a "dural tail" phenomenon.
No evidence of haemorrhage within the lesion.
Mild dilatation of the ipsilateral temporal and occipital horns of the lateral ventricle. No other intra or extra-axial enhancing lesion is present. There is minimal midline shift to the right. The basal cisterns are symmetric.
