Findings:
Interval resolution of the known planum sphenoidale meningioma with hemosiderin lined cavity involving the straight gyri bilaterally. No evidence of any nodular enhancement surrounding the resection cavity.
Right frontal cranioplasty is seen with post-operative dural enhancement in the right frontal pole and along the rostral cerebral falx on the right side. A small focus of signal loss with blooming artefacts is seen in the right basifrontal, correlating with post-operative changes.
Significant improvement of oedema involving the frontal lobes with residual white matter signal abnormality in the right frontal pole. The reduction of mass effect with normalisation of the frontal sulci. No midline shift.
A few, non-specific foci of FLAIR hyperintensity are noted in bilateral cerebral hemispheres. The brain parenchyma is otherwise unremarkable.
Known, small pineal cyst measuring approximately 5.5 x 9 mm and showing mild peripheral enhancement without any mass effect or hydrocephalus.
The pituitary gland is normal.
Unchanged right cerebellopontine angle well-circumscribed CSF intensity lesion, in keeping with right cerebellopontine angle arachnoid cyst.
The orbits, paranasal sinuses and mastoid air cells are clear.
Conclusion:
Satisfactory post-operative appearances after resection of a planum sphenoidale meningioma. No evidence of any residual tumour.
Residual white matter changes/oedema in the right frontal lobe.
Known pineal cyst and right cerebellopontine angle arachnoid cyst.
