MRI
A large, well-defined left parafalcine dural-based frontoparietal convexity extra-axial mass with a wide dural tail and CSF cleft, causes a mass effect on the underlying brain tissue, resulting in the effacement of cortical sulci and ipsilateral lateral ventricle with a midline shift of about 5 mm, measuring about 7.4 x 5 x 4.7 cm in the AP, TS, and CC dimensions, respectively.
It shows hypo-intense T1, heterogenous T2 signal, and mild diffusion restriction, with solid internal postcontrast enhancement.
No evidence of bone destruction. No acute infarction.
Multiple bilateral T2/FLAIR hyperintensities were seen involving the periventricular and subcortical white matter without diffusion restriction or mass effect suggesting mild small vessel disease.
Old lacunar infarction is noted in the right frontal lobe.
Capacious CSF spaces and basal cisterns compatible with the patient's age.
