Pleomorphic xanthoastrocytoma (PXA) is a unique meningocerebral glioma with a relatively favorable prognosis. PXA also possesses a variant with anaplastic features (aPXA), which is associated with poor outcomes. To date, few studies have examined the clinicopathologic importance of these anaplastic features. ⋯ aPXA is associated with poorer clinical outcomes compared with PXA. Gross total resection should be the goal of initial treatment. It remains unclear whether adjuvant radiation and chemotherapy are able to prevent progression or dissemination. Long-term monitoring of all patients is a critical step in management due to the potential for tumors to transform into higher-grade lesions.

The optimal treatment for aneurysmal subarachnoid hemorrhage (SAH) in elderly patients is controversial. Focusing on this specific population, we analyzed early outcomes after endovascular or neurosurgical treatment and developed a prognostic model to aid in clinical decision-making processes. ⋯ Because it was proven to be valid in quantitatively predicting treatment efficacy in elderly patients with ruptured aneurysm, the prognostic model is expected to enhance clinical decision-making processes by predicting the treatment-related risk for specific patients.

The impact of early physician follow-up on out-of-hospital outcomes after cerebral aneurysm treatment has not been studied previously. We investigated the association of early physician follow-up (within 30 days of discharge) with mortality and readmissions for elderly patients undergoing treatment for cerebral aneurysms. ⋯ In a cohort of Medicare patients undergoing treatment for cerebral aneurysms, we identified an association of early physician follow-up with decreased short-term post-discharge mortality, but increased 90-day readmissions. More studies on the impact of strengthening the post-discharge network on the outcomes of this population are warranted.

Glioblastoma (GB) is an infiltrative disease that results in microstructural damage on a cellular level. Fractional anisotropy (FA) is an important estimate of diffusion tensor imaging (DTI) that can be used to assess microstructural integrity. The aim of this study was to examine the correlation between FA values and overall survival (OS) in patients with GB. ⋯ FA values can provide prognostic information regarding OS in patients with GB. There is a correlation between FA-CEL values and Ki-67 proliferation index, a marker for malignancy. Noninvasive identification of more aggressive GB growth patterns might be beneficial for preoperative risk evaluation and estimation of prognosis.

To compare the results of anterior cervical discectomy and fusion (ACDF) combined with anterior cervical foraminotomy (ACF) and standalone ACDF for the treatment of cervical spondylotic radiculopathy (CSR). ⋯ For CSR with foraminal stenosis secondary to significant bony pathology that cannot be managed with standalone ACDF, ACDF combined with ACF is an effective and safe treatment strategy.
