Cavernous malformations in the pineal region are rare and difficult to anticipate from preoperative evaluation in patients with pineal apoplexy. We herein report the first case of a pineal cavernous malformation with superficial siderosis. Radiological findings were helpful in identifying the presence of the cavernous malformation. ⋯ Radiological findings of superficial siderosis on T2-star-weighted gradient-echo imaging are useful to making a diagnosis of cavernous malformation in cases of pineal apoplexy. They are also important for making the treatment decision to perform total mass resection, which is the best curative method for pineal cavernous malformations.

Rapid growth is a well-known property of glioblastoma (GBM); however, growth rates vary among patients. Mechanisms behind such variation have not been widely studied in human patients. We sought to investigate relationships between histopathologic features and tumor growth estimated from pretreatment magnetic resonance imaging scans. ⋯ Our findings show that high cellular density and thromboses are significant independent predictors of faster growth in human GBM. This finding underlines the importance of hypercellularity as a criterion in glioma grading. Furthermore, our findings are concordant with hypotheses suggesting hypoxia triggered by thromboses to be relevant for growth of GBM.

Effect of Interlaminar Epidural Steroid Injection in Patients with Central Cervical Spinal Stenosis.
To investigate the effect of interlaminar epidural steroid injection (ESI) for management of central cervical spinal stenosis-induced posterior neck pain. ⋯ Cervical interlaminar ESI appears to be a good treatment method for managing chronic posterior neck pain induced by central cervical spinal stenosis, especially when pain is refractory to oral medication.

Spinal artery aneurysms (SAAs) are extremely rare lesions that can occur in isolation or associated with vascular malformations. Herein, we present 3 unusual cases of SAAs and discuss imaging, diagnosis, and surgical management strategies. ⋯ Spinal artery aneurysms are rare lesions. Herein, we report 3 such cases and emphasize the importance of surgical management.

To investigate the ability of transforaminal lumbar interbody fusion (TLIF) to improve lumbar lordosis (LL). ⋯ For patients with neurogenic leg symptoms owing to single-level lumbar degenerative disease, whole LL was improved after TLIF as a result of spontaneous restoration of lordosis at the unfused lumbar levels.
