A solitary extra axial mass with a broad dural base at the junction of the right parieto-occipital lobes posteriorly is demonstrated. A thin CSF cleft is difficult to appreciate however is most conspicuous along the anterior aspect of the lesion with impression of cortical buckling. The lesion is predominantly isointense to adjacent brain parenchyma on T1, heterogeneous on T2 with several foci of intralesional gradient susceptibility artefacts representing blood products or calcium.
The lesion is vividly relatively homogeneously enhancing with a small dural tail. Diffusion restriction within the periphery and inferior aspects of the lesion. Extensive T2 signal hyper intensity involves the posterior frontal, superior parietal and posterior temporal lobes in keeping with vasogenic oedema.
Associated focal mass effect with sulcal effacement and effacement of the posterior horn and trigone of the right lateral ventricle.
No midline shift. No transtentorial or transforaminal herniation. No overlying hyperostosis identified.
Moderately extensive periventricular and deep subcortical white matter FLAIR/T2 signal hyper intensity is consistent with microvascular ischaemia.
The intracranial flow voids are preserved.
Solitary vividly enhancing extra-axial mass with a broad dural base is most likely in keeping with a meningioma.
