Kwesi Frempong Agyem MD, Presenter: Nothing to Disclose

Gain an understanding of the components of the pachymeninges, its relation to other anatomical structures, and its various functions. Develop an approach for assessing and describing the imaging appearance of the pachymeninges, and develop skills to localize abnormalities within the subdural or epidural spaces. Review specific benign etiologies (intracranial hypotension, osteomyelitis/discitis, trauma, soft tissue infections) that alter the appearance of the pachymeninges on MRI. Review specific malignancies that commonly involve the pachymeninges (meningiomas, secondary CNS lymphoma, small cell lung cancer, prostate cancer) and their typical appearances on MRI.
