A recent systematic review and meta-analysis found that there was a lack of consensus regarding risk factors for cerebral vasospasm in aneurysmal subarachnoid hemorrhage (aSAH). ⋯ In the first nationwide analysis of cerebral vasospasm, risk factors included younger age, female sex, smoking history, hemodynamic compromise, and clinical severity of aSAH. Recently proposed biomarkers, including leukocytosis and hypokalemia, were supported by our findings. This study may assist risk stratification and earlier detection of vasospasm.

The purpose of this study was to test the application of diffusion tensor imaging (DTI) in patients with hemifacial spasm (HFS), to make more accurate diagnoses before surgery and to judge the degree of recovery more accurately after surgical microvascular decompression. To our knowledge, this is the first study to test the validity of DTI for diagnosis and postsurgical evaluation of HFS. ⋯ The use of DTI improves diagnosis and treatment of HFS.

Extracranial metastases from atypical meningioma are not usually found; they are sometimes found in lung, bone or scalp, but atypical meningioma in the liver is extremely rare. ⋯ We have analyzed the cytological findings of a metastastic meningioma with particular focus on pathological and immunohistochemical assessment. These results could improve the knowledge of surgeons about meningioma types and guide them to solve clinical incidents.

Spine osteoblastomas (OBs) are relatively rare. In contrast to osteoid osteoma, radiologic and clinical manifestations of OB can be varied and atypical. Typical radiographic features in spinal OB include peritumoral bone sclerosis, bone marrow edema, and soft tissue edema. Atypical radiographic features include lesions involving ≥3 segments, lesions with extensive (≥3 segments) bone sclerosis, excessive edema (≥3 segments) of soft tissue and bone marrow, no intralesional calcification, and location in the vertebral body only. The aim of this study was to identify typical and atypical features of OB. ⋯ Our results show that >30% of spinal OB cases might have atypical radiographic features. In cases with atypical radiographic features, computed tomography-guided biopsies are recommended.

Late intramedullary spinal metastases from esthesioneuroblastoma: case report and prognostic implications.
Esthesioneuroblastoma (ENB) is an uncommon neuroectodermal tumor that originates from the olfactory mucosa and often recurs locally. Distant metastases of ENB have been described, but there are few reports of intramedullary metastases to the spinal cord. ⋯ Through the presentation of this case we hope to further contribute to a better understanding of this rare disease's prognosis.
