Imaging brain tumors – 4 – Other low grade gliomas
Brain tumors are one of the most common diagnoses addressed in neuroradiology. This covers a wide spectrum of disease, from primary brain tumors like gliomas and glioblastomas to secondary disease like metastases. This lecture covers the spectrum of the most common brain tumors, with an emphasis on primary brain tumors.
This video discusses imaging and genetic features of some less common low grade tumors like pilocytic astrocytoma, dysembryoplastic neuroepithelial tumor (DNET), ganglioglioma, and pleomorphic xanthoastrocytoma (PXA). These tumors are often seen in younger patients, many of whom will present with seizures. Surgery is often curative. There is a lot of imaging overlap for these tumors, especially DNET and ganglioglioma, which can appear very similar. However, the specific diagnosis is less important than knowing that a lesion may be a low grade glioma.
Additional videos in the playlist will address the imaging findings of other types of brain tumors, such as astrocytomas,oligodendrogliomas, and non-glial tumors. Other videos address general topics in brain tumor imaging, how to form a differential diagnosis for a brain tumor, and some challenge cases to apply your skills.
The level of this lecture is appropriate for radiology residents, radiology fellows, and trainees in other specialties who have an interest in neuroradiology or may see patients with brain tumors.
