On MRI, meningiomas are usually iso- to hypointense compared to grey matter on T1 weighted images and are iso- to hyperintense compared to grey matter on T2 weighted images. “Dural tail sign” is often seen where a contrast-enhancing meningeal tail extending from the primary tumor. This is a thickening of the dura adjacent to intracranial pathology, not pathognomonic to meningiomas and may occur with lymphoma and dural metastasis. The tail sign is seen in approximately 30% of cases (Sturges et. al 2008; Kraft et al 1997). A study by Sturges et. al to determine whether MRI characteristics would allow for prediction of subtype or grade found MRI characteristics did not allow for the prediction for meningioma subtype or grade in the study, emphasizing the necessity of histopathology for antemortem diagnosis (Sturges et. al,
