A 47-year-old male patient presented at our neurosurgery unit with neurogenic claudication symptoms. The patient had a history of low back pain and lower extremity pain for 2 years. ⋯ The patient was treated conservatively, and after weight loss in 13 months (body mass index of 29) he had full recovery of neurologic symptoms. A follow-up magnetic resonance image obtained 14 months after showed complete resolution of spinal epidural lipomatosis.

This study aimed to analyze the risk factors for secondary new vertebral compression fractures (SNVCFs) after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures. ⋯ Low BMD, high preoperative compression ratio, and high preoperative SI may be predictive factors for SNVCFs. In particular, to prevent AVCF, the injected bone cement should be distributed both evenly and symmetrically along the inferior-to-superior axis and the relative bone cement volume should not be excessive. Bone cement should be injected carefully to avoid upper adjacent intradiscal leakage. Prompt BMD correction is important to prevent SNVCF.

Preoperative magnetic resonance imaging with fat suppression (FS-MRI) is useful to detect bone marrow edema in osteoporotic vertebral fractures (OVFs) and thus can improve diagnostic accuracy and influence surgical strategy for percutaneous augmentation. The role of preoperative FS-MRI in preventing subsequent fractures after balloon kyphoplasty has not been investigated in initially subclinical fractures or fractures without obvious morphologic changes. ⋯ Surgical treatment according to preoperative FS-MRI did not reduce occurrence of subsequent OVFs and did not prolong fracture-free intervals within 12 months after kyphoplasty.

The term anterior communicating (ACom) aneurysm is often broadly used to classify any aneurysm formed on the A1-A2 junction, A1, A2, or ACom arteries. Aneurysm location has been associated with rupture risk, so whether an aneurysm is truly formed on the ACom artery can critically affect treatment decisions. The aim of this study was to reclassify broadly termed ACom aneurysms into 4 subgroups (A1, A2, true ACom, and A1-A2 junction) based on their location. ⋯ We found only 13% of the aneurysms initially referred to as ACom to be true ACom aneurysms. A more nuanced approach to ACom aneurysm classification may better guide management strategies.

Maximal aggressive meningioma resection has been suggested to provide the best tumor control rates. However, radical surgery of meningiomas located at the frontal skull base can be accompanied by impairment of adjacent cranial nerve function that negatively affects patients' quality of life. We, therefore, analyzed our institutional database for cases of new cranial nerve deficits and postoperative cerebrospinal fluid (CSF) leakage stratified by the extent of tumor resection. ⋯ We found high levels of new cranial nerve morbidity and CSF leakage after radical removal of frontal skull base meningiomas that included the adjacent dura. Thus, less aggressive surgery for frontobasal meningioma should be preferred.
