Evaluation of CTA, time-resolved 4D CE-MRA and DSA in the follow-up of an intracranial aneurysm treated with a flow diverter stent: Experience from a single case.

Endovascular treatment of giant, fusiform and dissecting aneurysms with flow diverter stents is becoming more and more popular. However, very few studies on the follow-up have been published. We describe a patient with a dissecting aneurysm of the right vertebral artery treated with flow diverter stent placement.

Polymicrogyria, Large Corpus Callosum and Psychomotor Retardation in Four-Year-Old Girl: Potential Association Based on MR Findings. A Case Report and Literature Review.

SUMMARY - We describe a child from consanguineous parents presenting mega corpus callosum (MegaCC), polymicrogyria, psychomotor retardation with swallowing difficulties and language impairment perhaps linked to the syndrome of megalencephaly-polymicrogyria-mega corpus callosum (MEG-PMG-MegaCC). Reviewing the literature, we speculate that MegaCC, psychomotor retardation and anomalies in cortical migration are the three pathognomonic features. The presence of additional possibly associated anomalies such as megalencephaly, indicates that the spectrum of linked malformations with this rare syndrome is broad and yet to be defined.

Flat panel angiography images in the post-operative follow-up of surgically clipped intracranial aneurysms.

Cerebral aneurysms must be monitored for varying periods after surgical and/or endovascular treatment and the duration of follow-up will depend on the type of therapy and the immediate post-operative outcome. Surgical clipping for intracranial aneurysms is a valid treatment but the metal clips generate artefacts so that follow-up monitoring still relies on catheter angiography. This study reports our preliminary experience with volumetric angiography using a Philips Allura Xper FD biplane system in the post-operative monitoring of aneurysm residues or major vascular changes following the surgical clipping of intracranial aneurysms.
