Review Case Reports
Neoplastic Cerebral Aneurysm From Metastatic Nonsmall Cell Lung Carcinoma: Case Report and Literature Review.
Intracranial cerebral aneurysms secondary to neoplastic etiology are a very rare occurrence. There have only been 5 published reports of intracranial cerebral aneurysms secondary to metastatic lung cancer. Four of those five previously published reports have been secondary to nonsmall cell lung carcinoma, and only 1 case caused subarachnoid hemorrhage. To our knowledge, this is the first report of a lung cancer-associated superior cerebellar artery aneurysm. ⋯ Intracranial neoplastic cerebral aneurysms are extremely rare entities, and a rare cause of subarachnoid hemorrhage. This diagnosis should be considered in patients who present with concurrent metastatic cancer and cerebral aneurysm or aneurysmal subarachnoid hemorrhage. Early initiation of chemotherapy may be beneficial in reducing the risk of tumor-particle embolization, but more research needs to be conducted to better understand this rare phenomenon.

Flow diversion has emerged as a highly effective treatment for intracranial aneurysms. ⋯ This study did not find any diagnostic yield in repeating cerebral angiography in adequately occluded aneurysms with the PED. We do not recommend repeat angiographic follow-up once aneurysms have achieved complete occlusion with the PED unless clinically warranted.

Multicenter Study
Prospective Multicenter Assessment of All-Cause Mortality Following Surgery for Adult Cervical Deformity.
Surgical treatments for adult cervical spinal deformity (ACSD) are often complex and have high complication rates. ⋯ All-cause mortality at a mean of 1.2 yr following surgery for ACSD was 9.2% in this prospective multicenter series. Causes of death were reflective of the overall high level of comorbidities. These findings may prove useful for treatment decision making and patient counseling in the context of the substantial impact of ACSD.

Flow diversion for basilar apex aneurysms has rarely been reported. ⋯ Flow diversion for the treatment of basilar apex aneurysms results in acceptable occlusion rates in highly selected cases. Both primary flow diversion and rescue after failed clipping or coiling resulted in a modified Rankin Scale score that was either equal or better than at presentation and the technology represents a viable alternative or adjunctive option.
