BACKGROUND: Osseous hyperpigmentation of the calvarium is an extremely rare finding with only few reported cases in literature. CASE DESCRIPTION: The case is of a 59-year-old Caucasian male who presented with an acute history of generalized tonic clonic seizures and progressive weakness of the right upper limb. He had a background history of a malignant melanoma which had been resected from his left external acoustic meatus 4 weeks prior. Neuroimaging of the brain showed an intra-axial space-occupying lesion in his left parietal lobe with no associated osseous changes...

BACKGROUND: Decompressive craniectomy or craniotomy is an effective method for reducing intracranial pressure in patients with traumatic brain injury. However, contralateral intracranial hematoma is a rare but serious complication. Recently, the endoscopic technique has been described as a minimally invasive, safe, and effective treatment for intracranial hematoma evacuation. To the best of our knowledge, no technical report has described bilateral traumatic intracerebral hemorrhage (TICH) evacuation using a neuroendoscope...

BACKGROUND: We report two cases who underwent mechanical thrombectomy using a stent retriever in advance of urgent carotid artery stenting (CAS) for carotid artery stenosis with free-floating thrombus (FFT). CASE DESCRIPTION: Two patients showing symptomatic carotid artery stenosis with FFT underwent urgent endovascular surgery due to progressive neurological symptoms. The first case showed an FFT with 70% internal carotid artery (ICA) stenosis. After the completion of the common and external carotid artery balloon and distal ICA filter protection, we deployed a 6-mm-diameter stent retriever in the distal part of the stenosis...

BACKGROUND: Anticoagulants prevent thrombosis in patients with atrial fibrillation (AF) and venous thromboembolism but increase the risk of hemorrhagic complications. If severe bleeding occurs with anticoagulant use, discontinuation and rapid reversal are essential. However, the optimal timing for resuming anticoagulants after using reversal agents remains unclear. Here, we report early cerebral infarction following the use of andexanet alfa (AA), a specific reversal agent for factor Xa inhibitors, in a patient with traumatic acute subdural hematoma (ASDH)...

BACKGROUND: Brain death testing is a rigorous process in which meticulous examination is crucial. In certain cases, ancillary testing is required. CASE DESCRIPTION: A 30-year-old male presented to the emergency room after a motor vehicle accident and was found to have subarachnoid hemorrhage and subdural hematoma. The examination was notable for the absence of brainstem responses. A nuclear medicine brain scan was completed which showed carotid arterial activity up to the level of the skull base with no intracranial arterial activity above with a "hot nose" sign consistent with brain death...

BACKGROUND: External ventricular drainage (EVD) is one of the most common neurosurgical procedures. Complications are rather rare and mostly include hemorrhage and infection. Hematomas may form during placement or even after the removal of an EVD. Regarding the latter, the literature is scarce, with only nine clinically significant cases reported. CASE DESCRIPTION: We present the case of a young woman who suffered an extensive hemorrhage after removal of an EVD, in the setting of a posterior fossa stroke...

BACKGROUND: Anterior transthoracic, posterolateral (i.e., costotransversectomy/lateral extracavitary), and transpedicular approaches are now utilized to address anterior, anterolateral, or lateral thoracic disk herniations (TDH). Notably, laminectomy has not been a viable option for treating TDH for decades due to the much lower rate of acceptable outcomes (i.e., 57% for decompressive laminectomy vs. over 80% for the posterolateral, lateral, and transthoracic procedures), and a higher risk of neurological morbidity/paralysis...

BACKGROUND: Focal cortical dysplasia (FCD) is one of the main causes of intractable epilepsy, which is amendable by surgery. During the surgical management of FCD, the understanding of its epileptogenic foci, interconnections, and spreading pathways is crucial for attaining a good postoperative seizure free outcome. METHODS: We retrospectively evaluated 54 FCD patients operated in Federal Center of Neurosurgery, Tyumen, Russia. The electroencephalogram findings were correlated to the involved brain anatomical areas...

BACKGROUND: Endovascular treatment of wide-necked bifurcation aneurysms remains challenging. Although the advent of PulseRider and Web has expanded treatment options, aneurysms with a large deviation from the parent artery axis remains difficult to treat. We present the case of a wide-necked bifurcation aneurysm that was misaligned with the angle between the long axis of the parent artery and the aneurysm and was successfully treated with Y-shaped PulseRider-assisted coil embolization...

BACKGROUND: Cerebral air embolism is a rare cause of acute ischemic stroke that is becoming increasingly well-described in the literature. However, the mechanism and severity of this type of injury can vary, with ischemia typically emerging early in the course of care. To the best of our knowledge, delayed ischemia in this setting has not yet been described. CASE DESCRIPTION: A stroke code was called for an unresponsive, hospitalized, 75-year-old man. A computerized tomography (CT) scan of the head revealed air within the right greater than left hemispheric cortical veins with loss of sulcation, concerning for developing ischemia, and CT angiography revealed absent opacification of the distal cortical vessels in the right anterior cerebral artery and middle cerebral artery territories...

BACKGROUND: Spinal navigation offers significant benefits in the surgical treatment of small thoracic intradural tumors. It enables precise tumor localization without subjecting the patient to high radiation doses. In addition, it allows for a smaller skin incision, reduced muscle stripping, and limited bone removal, thereby minimizing the risk of iatrogenic instability, blood loss, postoperative pain, and enabling shorter hospital stays. CASE DESCRIPTION: This video presents two cases demonstrating the application of spinal navigation technique for thoracic intradural tumors measuring <20 mm...

BACKGROUND: The retained medullary cord (RMC), caudal lipoma, and terminal myelocystocele (TMCC) are thought to originate from the failed regression spectrum during the secondary neurulation, and the central histopathological feature is the predominant presence of a central canal-like ependyma-lined lumen (CC-LELL) with surrounding neuroglial tissues (NGT), as a remnant of the medullary cord. However, reports on cases in which RMC, caudal lipoma, and TMCC coexist are very rare. CASE DESCRIPTION: We present two patients with cystic RMC with caudal lipoma and caudal lipoma with an RMC component, respectively, based on their clinical, neuroradiological, intraoperative, and histopathological findings...

BACKGROUND: Several changes in normal pressure dynamics on the brain occur with a decompressive craniectomy and subsequent cranioplasty. Dead space volume is an important factor contributing to intracranial volume postcranioplasty. A decrease in this volume due to negative suction drain along with relative negative pressure on the brain with the loss of external atmospheric pressure may lead to fatal cerebral edema. CASE DESCRIPTION: A 52-year-old gentleman with a 210 mL volume and middle cerebral artery territory infarction underwent an emergency craniectomy and 6 months later a titanium mold cranioplasty...

BACKGROUND: Sacral dural arteriovenous fistulas (AVFs) are often undiagnosed at the initial presentation due to their rarity. CASE DESCRIPTION: For 1 year, a 71-year-old man developed progressive motor and sensory disturbances in both legs. Magnetic resonance imaging showed spinal cord edema with mild contrast enhancement at the T9-10 and T12 levels. Although mild venous dilatation was observed only at the cauda equina level, it was not initially recognized as abnormal...
