3.9 x 2.5 x 3.2 cm right frontal lesion which is extradural and demonstrates small foci of internal high attenuation of the precontrast imaging, which may represent calcification or tiny regions of haemorrhage in this clinical setting. The lesion displays vivid contrast enhancement on the post contrast images. The features suggest a meningioma. There is underlying sulcal effacement but no underlying oedema.
Right convexity subdural haematoma measures 5 mm, previously 4 mm.
Associated mass effect causes effacement of underlying sulci, without midline shift.
No new intracranial haemorrhage.
No hydrocephalus.
Conclusion: Right convexity subdural haematoma. Right frontal likely meningioma. MRI is recommended.
Unremarkable CTA COW (not shown).
