Free Content Overcoming Atypical Imaging Features of Meningioma with High-Resolution Imaging and Advanced Imaging Techniques

Meningioma is the most common nonglial primary intracranial tumor and the most common extra-axial neoplasm. Most are well characterized by conventional MR imaging sequences. However, atypical imaging features of this common entity may be confused with alternative histologic diagnoses. In such cases, high-resolution imaging in conjunction with other imaging techniques, such as angiography, spectroscopy, susceptibility phase, and DTI, can be helpful in suggesting the proper diagnosis.

Learning Objective: To gain a better understanding of how high-resolution MR imaging, angiography, and advanced MR imaging techniques can indicate the diagnosis of meningioma in atypical cases.
