Check one of our Fellows’ Journal Club choice for the month:’Risk Factors for Epidural Hematoma Expansion and the Need for Surgery’

This study identifies critical factors associated with the initial size, progression, and management of EDHs. While most EDHs in our cohort showed no progressive enlargement or decrease in size, larger hematomas with more mass effect, arterial sources of bleeding, and active hemorrhage on imaging were associated with a higher likelihood of surgical intervention. Venous bleeds, even though some enlarged, were not treated surgically. Concomitant SAH emerged as the most significant predictor of EDH enlargement, highlighting the need for increased vigilance. Radiologists should recommend short-term follow-up in this subgroup. Future multicenter, prospective studies are needed to validate these findings and inform evidence-based guidelines for EDH care. By optimizing risk assessment and imaging strategies for follow-up, clinicians can improve outcomes while reducing radiology resource use.

Check one of our Editor’s choice for the month: ‘Are Deep White Matter Hyperintensities Associated with Amyloid-Related Imaging Abnormalities in Patients with Alzheimer Disease Treated with Lecanemab?’

In this retrospective cohort study, it was found that higher baseline burden of deep white matter hyperintensities, as quantified by the Fazekas score, is significantly associated with an increased risk of amyloid-related imaging abnormalities (ARIA) in patients with Alzheimer disease receiving antiamyloid immunotherapy (lecanemab).

The Plaque-RADS scoring system offers a clinically valuable tool for enhancing ischemic event risk stratification, particularly in patients with mild-to-moderate stenosis, and may guide personalized prevention strategies by identifying high-risk individuals on the basis of factors such as advanced age, male s*x, and smoking history. However, the association between Plaque-RADS and ischemic stroke lost statistical significance after adjusting for stenosis or max-NWI; this issue may require further investigation to confirm the clinical significance of this association.
Future research should focus on exploring whether the integration of Plaque-RADS with other biomarkers and imaging modalities could provide deeper insights into personalized prevention strategies for high-risk individuals.
