Endovascular treatment of posterior cerebral artery aneurysms is challenging because of the particular features of posterior circulation vessels. We performed a systematic review of the literature, to assess safety and efficacy associated to their endovascular treatment. ⋯ Endovascular treatment of posterior cerebral artery aneurysms is associated with increased degree of occlusion and low recurrence rate. However, a parent artery occlusion implies complications, even although most of them are minor events such as hemianopsia.

A case of hyperacute vasospasm, indicating a poor prognosis after aneurysmal subarachnoid hemorrhage (SAH), is reported, and a review is presented of the literature addressing use of nitric oxide (NO) donors in cases of refractory vasospasm and recurrent delayed cortical ischemias (DCI). ⋯ The review of the literature suggested that combined intravenous molsidomine with intraventricular SNP treatment reversed refractory, recurrent vasospasm and DCIs probably by addressing the hemoglobin NO sink effect, NO depletion, and decreased NO availability after aneurysmal SAH.

Review Case Reports
Cavernous malformation of the seventh cranial nerve- case report and review of literature.
Cavernous malformations (CMs) arising in the cranial nerves are rare. Only a few cases of facial nerve CMs have been reported in the literature. ⋯ CMs are very rare but should be included in the differential diagnosis of cerebellopontine angle masses.

Brain cognitive functions affect patient quality of life. The frontal lobe plays a crucial role in advanced cognitive functions, including executive function, meta-cognition, decision-making, memory, emotion, and language. Therefore, frontal tumors can lead to serious cognitive impairments. ⋯ The treatment may both resolve the effects of the tumor to improve cognitive function or cause permanent disabilities resulting from damage to healthy functional brain tissue. Previous studies have focused on the influence of frontal lesions and surgical treatments on patient cognitive function. Here, we review cognitive impairment caused by frontal lobe brain tumors.

Comparative Study
Lvis stent versus Enterprise stent for the Treatment of Unruptured Intracranial Aneurysms.
This retrospective study compared clinical and angiographic outcomes between LVIS and Enterprise stents. ⋯ Compared with Enterprise stents, LVIS stents may achieve greater complete or near-complete occlusion rate. There was no significant difference in procedural-related complications and clinical outcomes between LVIS and Enterprise stents.
