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 oligodendrogliomas, including low grade oligodendrogliomas (WHO grade 2) and anaplastic oligodendroglioma (grade 3). By definition, these tumors have 1p19q codeletion and IDH mutation. Oligodendrogliomas have better survival than astrocytomas. Higher grade tumors are more likely to have more mass effect, more enhancement, and less well-defined margins. However, oligodendrogliomas typically do not degenerate into glioblastomas.
Additional videos in the playlist will address the imaging findings of other types of brain tumors.
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.
