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.

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.

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.

Limited studies exist to support the safety of performing neuromodulation surgeries in patients whose anticlotting medication has been held. Here, we assess the safety of performing deep brain stimulation (DBS) in this patient population. ⋯ We found no increased risk of complications in patients routinely on anticlotting medication undergoing DBS lead placement. We show that our protocol was successful in balancing increased risks of bleeding and of thromboembolic events in this patient group.

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.
