It has been hypothesized that cervical foraminal stenosis affecting the spinal nerves results in changes in the multifidus and rotatores muscles. The results of this study demonstrated level- and side-specific correlations between fatty infiltration of the multifidus and rotatores muscles and severity of cervical foraminal stenosis. Given the segmental innervation of these muscles, the authors hypothesize that the increased fatty infiltration could be reflective of changes due to muscle denervation from cer
Patients with deep-seated arteriovenous malformations (AVMs) have a higher rate of unfavorable outcome and lower rate of nidus obliteration after primary stereotactic radiosurgery (SRS). The aim of this study was to evaluate and quantify the effect of AVM location on repeat SRS outcomes.
This retrospective, multicenter study involved 505 AVM patients managed with repeat, single-session SRS. The endpoints were nidus obliteration, hemorrhage in the latency period, radiation-induced changes (RICs), and favorable outcome. Patients were split on the basis of AVM location into the deep (brainstem, basal ganglia, thalamus, deep cerebellum, and corpus callosum) and superficial cohorts. The cohorts were matched 1:1 on the basis of the covariate balancing score for volume, eloquence of location, and
