To evaluate the clinical effect of kyphoplasty with the extrapedicular approach in the treatment of thoracic osteoporotic compression fractures, including upper, middle, and lower thoracic. ⋯ Extrapedicular kyphoplasty is safe and effective in treating thoracic osteoporotic vertebral compression fractures. It can rapidly relieve backache, restore the body height of the fractured thoracic vertebra, and correct kyphosis. In addition, it can improve patient quality of life.

Case Reports
Dysembryoplastic Neuroepithelial Tumor with an Enlarging Heterogeneously Enhancing Organizing Hematoma.
This report portrays an unusual presentation of a dysembryoplastic neuroepithelial tumor characterized by a chronic, enlarging, heterogeneously enhancing organizing hematoma. Differential diagnoses included the malignant transformation of a low-grade glioma, radiation necrosis, and radiation-induced cavernoma. A dysembryoplastic neuroepithelial tumor may have atypical characteristics and behavior, so continued follow-up with serial imaging is recommended.

Upper basilar artery (BA) aneurysms, which consist of basilar tip and BA-superior cerebellar artery aneurysms, are challenging to treat with microsurgical clipping. The anterior temporal approach is one surgical approach used to treat aneurysms in this region. Most previous reports on this approach have consisted of unruptured cases. Assessing mostly ruptured cases in this study, we describe the surgical technique, patient characteristics, and surgical outcomes. ⋯ With appropriate case selection, the anterior temporal approach was effective and safe for clipping of upper BA aneurysms, especially under subarachnoid hemorrhage conditions.

Cerebral aneurysm growth is significantly associated with aneurysm rupture, but risk factors for aneurysm growth are not well characterized. It is believed that altered intracranial hemodynamics may contribute to the pathophysiology of aneurysm growth, but these mechanisms are not fully understood. ⋯ The subset of unruptured cerebral aneurysms that demonstrate growth over time has a significantly higher mean PV-LWSS than stable aneurysms, as measured by quantitative magnetic resonance angiography. This information at the time of diagnosis may help predict future aneurysm growth, stratify rupture risk, and identify those aneurysms that should undergo prophylactic treatment.

During endovascular treatment of complex intracranial dural arteriovenous fistulas (DAVFs) of the transverse sigmoid sinus, it can be difficult to preserve the patency of the dural sinus. We have described the details of the transvenous balloon-assisted technique using Copernic RC balloon as a treatment option for patients with complex DAVFs of the transverse sigmoid sinus. ⋯ Transvenous Copernic RC balloon-assisted embolization of DAVFs in the transverse and sigmoid sinuses is safe and can offer complete occlusion of DAVFs and remission of clinical symptoms.
