Perfusion MR imaging and 1H spectroscopy: Their role in the diagnosis of microcystic and lipomatous meningiomas

Summary Microcystic and lipomatous meningiomas represent two of the recognised rare subtypes of meningiomas. We describe the CT and MR findings in one adult case of each subtype with emphasis on the diagnostic benefits of perfusion-weighted MR imaging (PWI) and/or proton magnetic resonance spectrosc...
