Cystic meningioangiomatosis with a multiple microcystic pattern. (a, b) DWI and T2WI demonstrated a low signal intensity nodule in the left parietal cortex and multiple small cysts surrounding it. (c) On post-contrast MRI, the nodule was remarkably enhanced. (d) Microscopically, fibroblast-like spindle cells were arranged in a spiral shape around multiple vessels, and the cortical neurons were entrapped within the lesion.
