The length, depth, and width were measured at every one-year follow-up MRI. The initial tumor volume, 25.5 cm3 (3.8 x 4.2 x 3.2 cm), regressed linearly to less than half, 9.9 cm3 (2.9 x 3.1x 2.2 cm). The right falx meningioma with calcification and surrounding edema (a) reduced in size, with less edema, along with an increase of calcification on CT and MRI over 7 years (b)

T2-weighted MRI. The initial volume (=length x depth x width x 0.5), 25.5 cm3 (3.8 x 4.2 x 3.2 cm), regressed linearly to less than half, 9.9 cm3 (2.9 x 3.1 x 2.2 cm) [Figure 1].
