An extra-axial vividly enhancing tumour has a broad base arising from the right frontal bone and anterior cranial fossa floor, indents but does not invade the frontal lobe, is partially calcified and heterogeneous, and measures 41 x 23 x 33 mm. A dural tail of enhancement extends both medial and posterolateral.
In addition, right convexity subdural blood and reactive dural enhancement are shown over the sylvian fissure and posterior frontal and anterior parietal lobes, 4.5 millimetres in maximum thickness, stable from prior CT.
Cerebral parenchymal signal intensity and architecture are otherwise within normal limits.
Normal flow voids are demonstrated in the major arteries at the base of the brain. No hydrocephalus.
Conclusion: Right frontal meningioma with extensive dural tail enhancement merging with enhancement related to the subacute subdural haematoma
Right subdural convexity haematoma
