Summary
Infratentorial cerebral cavernous malformations (CCMs) carry a higher risk of symptomatic hemorrhage compared to supratentorial CCMs. This finding aids in clinical decision-making for patients with CCMs.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Malformations
Background:
- Cerebral cavernous malformations (CCMs) present a spectrum of intracranial hemorrhage risks, complicating management and patient counseling.
- Existing evidence on CCMs is heterogeneous, necessitating standardized data for informed clinical decisions.
Purpose of the Study:
- To delineate symptomatic burden differences in CCMs based on anatomic location.
- To provide evidence-based insights for improved clinical decision-making and patient counseling regarding CCMs.
Main Methods:
- Retrospective cohort analysis of patients diagnosed with CCMs between 1990 and 2018.
- Primary outcome assessed was acute symptomatic hemorrhages.
- Analysis included 632 CCMs across 438 patients, evaluating lesion location and symptomatic presentation.
Main Results:
- Infratentorial CCMs showed a significantly higher likelihood of symptomatic hemorrhage (29%) compared to supratentorial CCMs (25%).
- A linear mixed-effects regression model confirmed infratentorial location as a significant predictor of symptomatic hemorrhage (OR, 1.81; P = 0.008).
- Mean age at diagnosis was 50 years, with 64% of patients presenting with initial symptoms.
Conclusions:
- Infratentorial cavernous malformations are more prone to symptomatic hemorrhages at diagnosis and during follow-up.
- Anatomic location is a critical factor influencing the symptomatic presentation of CCMs.
- These findings support tailored clinical management strategies based on CCM location.
