Review
Current status of pipeline embolization device in the treatment of intracranial aneurysms: a review.
Pipeline embolization device (PED) implantation is a novel endovascular treatment option for the treatment of intracranial aneurysms. It is emerging as a useful alternative to coiling and to open surgery, and its use is increasing worldwide. We performed a literature review to examine its efficacy, technical challenges, and safety. ⋯ PED offers an alternative to endovascular coiling for aneurysms with complex morphology. The indication for its use has evolved from the limited scope of treatment of giant aneurysms with wide necks to the inclusion of smaller aneurysms. The procedural safety profile of PED is comparable with or possibly superior to balloon-remodeling or stent-assisted coil embolization in specific circumstances. However, questions remain regarding the incidence of post-procedural subarachnoid hemorrhage. Ongoing monitoring and meticulous documentation of PED postimplantation safety is strongly recommended.

Case Reports
The transconjunctival transorbital approach: a keyhole approach to the midline anterior skull base.
To report an initial experience with a medial transorbital approach to the midline skull base performed via a transconjunctival incision. ⋯ The transconjunctival medial orbital craniectomy provides a minimally invasive keyhole approach to lesions located anteriorly along the anterior cranial fossa that are in the midline with lateral extension over the orbital roof. Based on our initial experience with this technique, the working space afforded limits complex surgical dissection; this approach is primarily well suited for less extensive pathology.

To review the management of aneurysms arising at the origin of a duplicated middle cerebral artery (DMCA), which is an extremely rare entity. ⋯ Although all previously published clinical cases of internal carotid artery-DMCA aneurysms were treated surgically, conservative management with follow-up is a viable option in very small unruptured aneurysms.

Case Reports
Shunt-related intracranial abscess caused by Staphylococcus lugdunensis in a hydranencephalic patient.
Staphylococcus lugdunensis is a coagulase-negative staphylococcus with aggressive and rapidly progressive infectious behavior. This organism has emerged as an important pathogen implicated in both community-acquired and nosocomial infections, including meningitis, brain abscess, catheter-related bacteremia, and ventriculoperitoneal shunt infection. ⋯ This case suggests that if Staphylococcus lugdunensis is identified, a virulent and prolonged clinical course with the production of destructive lesions, similar to those with S. aureus, should be expected. A course of antibiotic therapy and aggressive management that may include surgical treatment will be needed.
