Cystic Meningioma Simulating Arachnoid Cyst: Report of an Unusual Case

Figure 1

CT scan of the brain. A hypodense, extra-axial image is observed (asterisk), in the right frontoparietal region which imprints over the adjacent brain parenchyma. Lesion hypodensity is similar to the cerebrospinal fluid. A small mural hyperdense nodule (red arrow) is also identified.
