Transient Global Amnesia Following Coil Embolization for a Basilar-tip Aneurysm: Case Reports of Two Patients

Transient global amnesia (TGA) can be caused by medications, ischemia, metabolic abnormalities, and seizures. We describe two cases of TGA following coil embolization for a basilar-tip aneurysm. A 73-year-old woman developed transient acute anterograde amnesia after coil embolization for a basilar-t...

description Transient global amnesia (TGA) can be caused by medications, ischemia, metabolic abnormalities, and seizures. We describe two cases of TGA following coil embolization for a basilar-tip aneurysm. A 73-year-old woman developed transient acute anterograde amnesia after coil embolization for a basilar-tip aneurysm. Diffusion-weighted imaging (DWI) revealed an ischemic lesion in the anterior nucleus of the thalamus. A 67-year-old woman developed transient acute amnesia after a stent-assisted coil embolization of a basilar-tip aneurysm. A DWI showed ischemic lesions in the anterior nucleus of the thalamus. Any ischemic changes to areas of the anterior nucleus that are fed by the thalamoperforating and premammillary arteries should be considered in a differential diagnosis for TGA in patients who have undergone coil embolization for a posterior circulation cerebral aneurysm.
