Abstract
The pathology of cystic structures in and around meningiomas is discussed in Chaps. 1 and 3. Cystic meningiomas are often misdiagnosed on computed tomography (CT) and magnetic resonance imaging (MRI), particularly as gliomas (Figs. 11.1, 11.2, 4.5, 4.14, 6.8). Helpful CT features are: contrast enhancement of the solid part, clear separation between this portion and the cystic part and demonstration of dural attachment. These are demonstrated particularly well with the multiplanar facility of MRI (Fig. 4.14). Angiography may be helpful by demonstrating the extra-axial location of the lesion and predominantly meningeal blood supply [167, 216, 225, 298]. Nevertheless a biopsy is usually mandatory for final diagnosis.
