Case Reports
Endovascular treatment of a left carotid artery "bowtie" pseudoaneurysm with a covered Wallgraft stent.
The authors present an unusual case of a young male patient with a large left common carotid artery pseudoaneurysm in a shape similar to that of a bowtie treated with a covered Wallgraft. The Wallgraft is a covered stent originally designed to be used in the treatment of tracheobronchial fistula and peripheral arterial applications. The favorable outcome of this case illustrates its endovascular application in nonsurgical traumatic injuries of the carotid artery.

To assess the magnetic resonance (MR) imaging characteristics of spinal intramedullary ependymomas. ⋯ Ependymomas occur most often at the upper cord rather than in the conus medullaris and filum terminale. Of the cervical and thoracic ependymomas, most were cellular or epithelial types. Papillary ependymomas occurred exclusively in the conus medullaris and filum terminale. Rostral and caudal cysts are frequently associated with intramedullary ependymomas. Clear tumor margins, more uniform enhancement, and central locations can help differentiate ependymomas from other intramedullary spinal cord tumors.
