Vertebral artery injury is known to potentially occur in conjunction with blunt cervical spine trauma. Rarely, these injuries present bilaterally as complete occlusions. Twelve cases of bilateral vertebral artery occlusions after closed cervical spine trauma have been described in the reported data, nearly all of which demonstrated signs and symptoms of vertebrobasilar insufficiency and ischemia. ⋯ We present our patient's case as a rare illustration of a bilateral vertebral artery occlusion after blunt cervical spine trauma without clinical vertebrobasilar ischemic sequelae.

To report our experience of the management of 60 patients with craniopharyngioma with endoscopic endonasal surgery (EES) and evaluate the feasibility and safety of EES for craniopharyngiomas. ⋯ EES can provide surgeons with excellent exposure and can achieve a high extent of removal of most craniopharyngiomas, even those with intraventricular extensions, In our view, vascularized pedicled septal flaps and in situ bony flaps were used in skull base reconstruction.

Secondary brain injuries, such as delayed cerebral infarction (DCI), are the leading causes of disability after subarachnoid hemorrhage (SAH). Detecting DCI may be challenging, especially for patients presenting an altered level of consciousness. ⋯ Multiple secondary complications (DCI, seizures, hydrocephalus) may occur after SAH but are clinically difficult to diagnose. A multimodal evaluation (transcranial Doppler, CT or magnetic resonance imaging, electroencephalography) is useful in order to detect and treat late complications.

Parasagittal and parafalcine (PSPF) meningiomas recur more frequently than other intracranial meningiomas owing to the difficulty in achieving gross total resection. The present study investigated the preoperative magnetic resonance imaging (MRI) features for the prediction of progression/recurrence (P/R) in benign PSPF meningiomas with an emphasis on the apparent diffusion coefficient (ADC) values. ⋯ The preoperative ADC values and ratios for the prediction of P/R offer additional valuable information for the treatment planning for PSPF meningiomas.

Successful resection of arteriovenous malformation (AVM) depends on preoperative assessment of the detailed morphology of the AVM. Simultaneous detailed three-dimensional visualization of the feeding arteries, draining veins, and surrounding structures is needed. The aim of this study was to evaluate the usefulness of high-resolution three-dimensional multifusion medical imaging (HR-3DMMI) for preoperative planning of AVM resection. ⋯ HR-3DMMI technique demonstrated the precise locations of feeding arteries, draining veins, and surrounding important tissues, such as corticospinal tract and arcuate fiber, preoperatively and estimated the appropriate route for resection of the AVM. HR-3DMMI is expected to be a very useful support tool for surgery of AVM.
