At the time of last follow-up, improvement in radiculopathy was observed in 94% of the resected PLL group compared with 81% of the unresected PLL group (P = 0.008). After controlling for confounders, PLL resection had 3.8 times greater odds of leading to postoperative improvement in radiculopathy. CONCLUSIONS ACDF leads to a high rate of success in improvement of preoperative radiculopathy. Excision of PLL during surgery leads to 3.8 times greater odds of improvement in this symptom, with no significant difference in the complication rate. BACKGROUND Rheumatoid meningitis is a rare manifestation of autoimmune rheumatoid arthritis. CASE DESCRIPTION A 70-year-old man with rheumatoid arthritis had presented with speech difficulties and limb weakness. Magnetic resonance imaging of his brain demonstrated diffuse meningeal enhancement. A biopsy confirmed the presence of rheumatoid meningitis. CONCLUSION In the present report, we have discussed the diagnostic and therapeutic approach to rheumatoid meningitis. BACKGROUND Few studies have examined the usefulness of intraoperative magnetic resonance spectroscopy (iMRS) for identifying abnormal signals at the resection margin during glioma surgery. The aim of this study was to assess the value of iMRS for detecting proliferative remnants of glioma at the resection margin. METHODS Fifteen patients with newly diagnosed glioma underwent single-voxel 3-T iMRS concurrently with intraoperative magnetic resonance imaging-assisted surgery. Volumes of interest (VOIs) were placed at T2-hyperintense or contrast-enhancing lesions at the resection margin. In addition to technical verification, the correlation between the MIB-1 labeling index (a pathologic feature) and metabolites measured using iMRS (N-acetyl-L-aspartate [NAA], choline [Cho], and Cho/NAA ratio) was analyzed. RESULTS iMRS was performed for 20 VOIs in 15 patients. Fourteen (70%) of
