Summary
A rare case of extensive corpus callosum (CC) ischemia following anterior cerebral artery aneurysm rupture caused a near-complete split-brain syndrome. This highlights a rare vascular complication of subarachnoid hemorrhage (SAH).
Area of Science:
- Neuroscience
- Vascular Neurology
- Neurocritical Care
Background:
- Subarachnoid hemorrhage (SAH) from anterior cerebral artery (ACA) aneurysms can lead to delayed cerebral ischemia and vasospasm.
- Ischemic infarction of the corpus callosum (CC) is a rare complication of SAH.
- Isolated split-brain syndrome due to vascular damage to the CC is exceptionally uncommon.
