STUDY DESIGN: Retrospective case series. OBJECTIVES: We retrospectively evaluated the clinical efficacy of postganglionic nerve block in symptomatic Schmorl nodules (SNs). SUMMARY OF LITERATURE REVIEW: SNs are common lesions that are often asymptomatic. In certain cases, SNs have been reported to cause severe axial back pain, thereby considerably impacting patients' quality of life. No consensus currently exists on the treatment of symptomatic SNs. MATERIALS AND METHODS: From October 2015 to October 2017, a total of 21 patients with symptomatic SNs diagnosed by magnetic resonance imaging (MRI) that did not respond to conservative treatment after 4 weeks were included in the study. All patients received postganglionic nerve block. We evaluated effective pain relief (improvement of back pain of more than 50% compared with before the intervention) and functional improvements, assessed by visual analogue scale (VAS) and Oswestry Disability Index scores obtained at 4 hours, 4 weeks, 8 weeks, 3 months, and 6 months after the procedure. RESULTS: Symptomatic SNs were more common at the L2-3 level, and the lower end plate was more commonly involved than the upper end plate. Eighteen of the 21 patients (85.7%) showed effective pain relief, and no deterioration was observed within the follow-up period. Throughout the follow-up period, the VAS remained significantly improved compared to before the procedure (p < 0.05). Complications were not reported in any cases. CONCLUSIONS: Postganglionic nerve block for symptomatic SNs that do not respond to conservative treatment is a non-invasive modality for pain relief.

MR finding of melanoma shows peculiar signal intensity based on paramagnetic effect of melanin or intratumoral hemorrhage, which displays decreased T1 and T2 relaxation times in many cases. Authors report MR findings in two cases of intracranial metastatic melanoma, which is pathologically confirmed by operation.

The authors report a very unusual case of ruptured aneurysm by direct vessel invasion of anaplastic oligodendroglioma (WHO grade III) confirmed by histopathological examinations. As local invasion is the hallmark of malignant gliomas, malignant glial tumors invade neighboring structure and often cause microscopic endothelial proliferation, telangiectasias in small arteriols, but direct arterial invasion by glioma is very rare. Possible mechanisms of intracranial aneurysm development by glioma are thought to be related to the close proximity to the tumor, perivascular basement membrane breakage due to high tumor pressure and increased regional blood flow through the feeding artery of tumor. The aneurysm and tumor were treated in a single operation simultaneously.
