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.

Anaplastic meningiomas are rare tumors with a poor prognosis, even after complete surgical resection and radiotherapy. There has been limited evidence with respect to the clinical factors and their effects on the course of the disease. Various retrospective studies have not been able to provide clear evidence of standardized treatment, usually presenting contradictory results. The aim of this study was to evaluate the prognostic factors influencing the progression-free survival (PFS) and overall survival (OS) of anaplastic meningiomas, with a particular focus on the roles of the extent of resection and postoperative adjuvant radiotherapy. ⋯ The extent of resection in anaplastic meningiomas is correlated with a better outcome. However, resection alone is not sufficient for the long-term control of anaplastic meningiomas. Adjuvant radiotherapy is an essential component in the adjuvant treatment of anaplastic meningiomas, including for patients undergoing GTR. Further investigations through which to improve adjuvant therapy options are necessary to improve meningioma therapy.

The aim of this study was to introduce resting-state functional magnetic resonance imaging (rest-fMRI) capability for brain tumor surgical planning. rest-fMRI is an emerging functional neuroimaging technique potentially able to provide new insights into brain physiology and to provide useful information regarding brain tumors in preoperative and postoperative settings. rest-fMRI evaluates low-frequency fluctuations in the blood oxygen level-dependent signal while the subject is at rest during magnetic resonance imaging examination. Multiple resting-state networks have been identified, including the somatosensory, language, and visual networks, which are of primary importance for surgical planning. We discuss the feasibility of rest-fMRI examination before and after surgical resection of brain tumors in routine clinical practice and the usefulness of the information obtained for surgical planning in brain tumor resection. rest-fMRI is particularly useful for patients who are unable to cooperate with the task-based paradigm, such as children or patients who are sedated, paretic, or aphasic. Although standardization and validation of rest-fMRI are still ongoing, this technique is feasible and valuable and can be implemented for routine clinical surgical planning.

Spontaneous subgaleal abscess associated with lung adenocarcinoma: first description of this unusual association.
Primary, spontaneous, or de novo subgaleal abscesses represent extremely rare lesions usually related to patients with risk factors and predisposing conditions for infections. They are associated with high morbidity, and a proper diagnosis can be misleading. To the best of our knowledge, this is the first reported case of a de novo subgaleal abscess not related to previous traumatic head injury and associated with lung adenocarcinoma. ⋯ We strongly suggest a patient global assessment in the event of subgaleal abscess without history of traumatic head injury, to treat eventual associated findings as soon as possible.

Stroke is a major factor of morbidity in the patients with Takayasu arteritis (TA). Restenosis is more common with endovascular intervention than after bypass surgery, but vascular anastomosis is difficult due to calcification involving the whole thickness of the arterial wall in the burned-out stage of TA. We report a case of advanced TA in which endovascular treatment of the left subclavian artery improved cerebral blood flow (CBF) over a wide range of perfusion in the posterior and anterior circulation. ⋯ As collateral circulation is common in advanced TA, the ischemic area is large when the remaining proximal large vessels are occluded. Therefore revascularization of the remaining branch of the aorta in advanced TA may protect against a wide range of perfusion.
