Summary
Thalamic cavernous malformations (CMs) are rare but carry a high risk of bleeding. A transcortical approach through the superior temporal gyrus offers a safe surgical corridor for removal, preventing new neurological deficits.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Cerebrovascular Disease
Background:
- Cavernous malformations (CMs) are the second most common cerebral vascular lesion, typically found in the subcortex or white matter.
- Thalamic CMs are rare but have a high annual bleeding risk (>5%) and rebleeding rate (>60%), often within a year.
- The deep location and proximity to eloquent brain areas make thalamic CMs surgically challenging.
