- Radiogenomics Provides Insights into Gliomas Demonstrating Single-Arm 1p or 19q Deletion
The results of this study show that imaging and survival data of tumors with single-arm 1p or 19q deletion are equivalent to IDH-mutant astrocytomas rather than oligodendrogliomas. Not only does this support our understanding of the neurobiologic underpinnings, but it also provides reassurance in the management of these tumors with 1p- or 19q-unideletion as astrocytomas, in keeping with the WHO classification.
- DWI-Detected Ischemic Lesions after Endovascular Treatment for Cerebral Aneurysms: An Updated Systematic Review and Meta-analysis
This systematic review and meta-analysis found the incidence of new postprocedural DWI-detected ischemic lesions after endovascular treatment for intracranial aneurysms to be 47.0% (95% CI, 39.6%–55.8%), regardless of the endovascular procedure used. Studies have shown that almost half of these lesions are asymptomatic, and if small (<5 mm), these lesions have been shown to regress without negative effect on clinical outcome.
