To evaluate the effect of early depressive burden on PROMs in the setting of cervical disc replacement (CDR). ⋯ Patients with a greater depressive burden were more likely to experience greater magnitudes of improvements in PHQ-9 at both 6-week and final follow-up and experience clinically meaningful improvement in depressive symptoms. Patients with a lesser depressive burden were more likely to experience a greater magnitude of improvement in PROMIS-PF at final follow-up and experience clinically meaningful improvement in physical function.

A cyst with mural nodule(s) (CMN) is a rare imaging finding of cerebellar metastasis (CMET). It is a great challenge to differentiate it from cerebellar hemangioblastoma (CHB). In the present study, we explore the differences in the magnetic resonance imaging (MRI) characteristics of the 2 tumors. ⋯ When CMN is detected in the cerebellum on MRI, older age, multiple mural nodules, absence of vascular flow voids, isointense or hypointense mural nodule on fluid-attenuated inversion recovery sequence, restricted diffusion of the mural nodule, mildly enhanced mural nodules, and a ring-enhanced pattern of the cyst wall are the clinical and imaging features that strongly indicate the likelihood of metastasis, rather than CHB.

Anterior petrosectomy demands localization of the internal auditory canal (IAC) for safe bone drilling and maximum exposure. Various techniques have been described in the literature, each with shortcomings. We propose a new technique to localize the internal acoustic meatus (IAM) using more consistent anatomical landmarks. ⋯ The FO-FS-IAM angle variance was much lower than the analogous angles measured by Garcia-Ibanez and Fisch techniques, making it a more reliable and effective tool for localizing the IAM.

To determine the cost-effectiveness of mechanical thrombectomy (MT) versus best medical management (BMM) in patients aged ≥80 years. ⋯ This study utilized stroke outcomes data for patients aged ≥80 years to conduct a cost-effectiveness analysis. MT was found to be less cost-effective than BMM with and without IV tPA.

Cognitive dysfunction is a serious complication of moyamoya disease (MMD) in adults, and reduced cerebral blood flow (CBF) might be the potential cause. We aimed to explore the correlation between cerebral hemodynamics and cognitive function in adults with MMD by using three-dimensional pseudo-continuous arterial spin labeling (3D-pCASL). ⋯ The 3D-pCASL can find the hypoperfusion area of CBF in adults with MMD, and hypoperfusion in specific brain regions may cause cognitive dysfunction even in asymptomatic patients.
