Glioblastoma with Rhabdoid Features: Report of Two Young Adult Cases and Review of the Literature.
There are few previous reports of glioblastoma in young adults, in particular, of the very rare recently proposed rhabdoid or epithelioid types. ⋯ Glioblastoma with rhabdoid features may represent a specific pattern of clinical progression that emerges from histologic glioblastoma types.

The three-dimensional (3D) endoscope is a novel tool that provides stereoscopic vision and may allow for improved dexterity and safety during surgical resection of ventral skull base lesions. We describe here the cumulative experience available in the neurosurgical literature. ⋯ Our findings suggest that 3D endoscopy provides improved surgical dexterity by affording the surgeon with depth perception when manipulating tissue and maneuvering the endoscope in the endonasal corridor.

Case Reports
Stent assisted coiling of aneurysm in a persistent primitive lateral vertebro basilar system.
Fenestrations of cerebral arteries are relatively common. Knowledge of their structure has recently gained clinical significance with increasing awareness of fenestration aneurysms. Persistent primitive lateral vertebrobasilar (PPLVB) anastomoses are an extreme end of the embryologic mishaps causing these fenestrations, and their occurrence has only been reported twice. ⋯ The unique anatomy of these aneurysms and relation with important perforators and brainstem make surgery extremely difficult and require advanced endovascular techniques like balloon remodeling and stent assistance. Three-dimensional rotational angiography can help in providing clarity to the aneurysmal anatomy and planning treatment. The purpose of this case report is to bring to notice the possibility of such aneurysms and use the unique anatomy to understand various tools available in the endovascular surgeon's armamentarium.

Case Reports
Encountering a basal vein of Rosenthal variant during the anterior transpetrosal approach.
The basal vein of Rosenthal (BVR) is important in intracranial surgery, including skull base surgery. We report a case of petroclival meningioma in which a BVR variant drained into the tentorial sinus. ⋯ To our knowledge, this is the first study to describe surgery using the ATPA and involving a BVR variant, in which the vein was imaged successfully preoperatively using sliding-thin-slab MIP.
