Aneurysm recurrence after Pipeline Embolization Device (PED) placement can be caused by oversizing of the stent as well as poor wall apposition, both of which can lead to elongation. The objective of this study was to assess whether a novel parameter for measuring device elongation based on two-dimensional imaging could be predictive for persistent aneurysm filling after treatment with the PED. ⋯ Our data suggest that a novel parameter based on two-dimensional angiography may serve as a rapid technique to measure device elongation and predict occlusion of supraclinoid aneurysms after PED placement.

Blast-induced traumatic brain injuries (bTBIs) are increasingly frequent in civilian settings. We present the first study of individuals with bTBI in Iraq. The study focuses on one of the deadliest suicide car bomb attacks in Iraq and uses it to show the devastating nature of bTBIs. ⋯ This study sheds light on the devastating nature of bTBIs. Neurosurgeons worldwide need to be mindful of the unique triaging, diagnostic, and management requirements of these injuries.

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.

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.
