PROCEDURE: MRI BRAIN, Multi-planar multi-sequence (T1, T2 and FLAIR) images were
obtained. Post contrast images also taken.
CLINICAL INDICATION: diagnosed patient with extra ventricular neurocytoma. Surgery done on
28/05/2024. ? Recurrence.
COMPARISON: Comparison with previous MRI report done on 20/12/2023

FINDINGS:
There is an extra axial mass lesion in the posterior fossa extend above to supra tentorial region.
The lesion measuring 43 (Ap)x 49(Lat) x 63(Trans) mm.

R

There is mass effect on upper part of cerebellum, superior cerebella peduncle, pons, right
occipital horn and occipital lobe.

-

There is perilesional oedema involving right temporal and occipital lobes.
Mild prominence of lateral and 3rd ventricles. 4th ventricle is compressed by the mass.
VP shunts in situ with the tip in the right lateral ventricle.
The lesion is hypointanse in T1W and hyperintense in T2W and FLAIR with heterogeneous
contrast enhancement.
No blooming artefact to suggest calcification or haemorrhages.
No brain herniation or acute infarctions.

R

Rest of cerebral hemispheres, cerebellum and brain stem show normal signal characteristics.
Paranasal sinuses are normal. Normal clival signal is seen.
Visualized upper cervical spine appears normal.

E

No abnormal occlusion or stenosis noted in main arteries.

COMMENT/SUMMARY:

P

· An extra axial mass lesion in the posterior fossa extend above to supra tentorial region
with mass effect and compression on 4th ventricle causing hydrocephalus.
· Features are suggestive of residual/recurrence of known neurocytoma.
