Findings:
Compared to the previous study unchanged appearance of the multiple supra- and infratentorial meningiomas including convexity, falcine, tentorial, parasellar, sphenoid wing and CPA meningiomas. There is also widespread dural thickening.
Unchanged to the previous study a blooming artefact is seen in the right insular region, correlating to a small intra-axial lesion with mixed signal on the T2w (SE 5, IM 13), likely in keeping with a cavernoma.
There is a right temporal approach ventriculostomy catheter with the tip terminating in the left lateral ventricle. The ventricles are slit-like in appearance, unchanged to the previous study. Minimal, bilateral hygroma is seen. There is no midline shift.
Known, unchanged focal hypertrophy of the nasal pharyngeal adenoid.
Diffuse calvarium thickening secondary to chronic shunting is noted.
Conclusion:
Stable appearance of the radiation induced bilateral supra- and infratentorial meningiomas.
Small right insular cavernoma.
Chronic overshunting with minimal bilateral hygromas and calvarium thickening.
