Case Reports
Endovascular treatment of iatrogenic intracranial pseudoaneurysm following stent angioplasty.
Intracranial pseudoaneurysm (IPA) is a rare disease entity associated with blunt trauma or penetration injury and less likely surgical or endovascular procedure. Decision of the therapeutic option is difficult and challenging in the treatment of iatrogenic pseudoaneurysm from the middle cerebral artery (MCA) that is necessary to maintain. We report our experience of reconstructive treatment of iatrogenic IPA, which was developed after stenting and balloon angioplasty, in the left MCA with overlapping Enterprise stents.

Mortality in acute ischemic middle cerebral artery (MCA) stroke ranges from 5% to 45%. We identify a vascular imaging sign, presence of "prominent anterior temporal artery" on computed tomography (CT) angiography (CTA) and investigate whether it predicts mortality in acute M1-MCA occlusions. ⋯ Presence of prominent anterior temporal artery in M1-MCA occlusions on CTA identifies a group of patients with reduced case fatality. The mechanism is likely related to a reduced chance of malignant cerebral edema.

Ascent™: a novel balloon microcatheter device used as the primary coiling microcatheter of a basilar tip aneurysm.
Intracranial aneurysms undergoing balloon-assisted endovascular repair are particularly challenging given the concurrent use of one or more catheters in addition to the primary coiling microcatheter. Here, we describe a previously unreported novel device where a balloon catheter was used as the primary coiling microcatheter, thereby eliminated the need for additional catheters.

Case Reports
Nonblinding, penetrating orbital injury with pontine and cerebellar involvement secondary to antenna trauma.
Traumatic pontine and cerebellar damage originating from ocular injury has been documented in the past; however, no report has been made about an orbital trauma causing injury to the pons and cerebellum with associated neurological symptoms while leaving the globe, visual pathway, and ocular controls intact. ⋯ Pontine and cerebellar injury can occur from trauma that originated in the orbit and traveled posteriorly through the cranium without causing any overt damage to ocular structures but still causing other associated neurological problems.

This report describes a rare complication in a woman who underwent thoracic spinal surgery. One month postoperatively, her rehabilitation was interrupted by the development of a severe headache, nausea, vomiting, and a right-side occulomotor nerve palsy. ⋯ The CSF was seen to track into the right pleural space via a dural-pleural fistula. Surgical repair of the fistula led to a definitive resolution in symptoms, thus highlighting the importance of early recognition of this highly unusual complication.
