Hemorrhagic astroblastoma: atypical presentation of a rare tumor. Illustrative case.

Background: Astroblastoma is an extremely rare tumor of the central nervous system, and its origin and validity as a different entity are still being debated. Because of its rarity and similarities to other glial neoplasms, it is often misdiagnosed, impacting treatment and outcomes.

Observations: Astroblastoma is very rare and mainly affects children and young adults.

Intentional staged embolization via the "highway bypass" using a radial artery graft for a large posterior circulation aneurysm: illustrative case.

Background: The presence of significant tortuosity in access routes to aneurysms can interfere with catheter guidance and manipulation and significantly impact treatment strategies.

Observations: In this report, the authors combined intentional staged aneurysm embolization with the construction of a new direct access route, which they call a "highway bypass," for a symptomatic posterior circulation cerebral aneurysm that was difficult to access with a catheter. Notably, the highway bypass is used for catheter passage, and technical tips should be considered.

Iatrogenic pseudoaneurysm formation of the anterior cerebral artery following placement of an external ventricular drain: illustrative case.

Background: External ventricular drains (EVDs) provide an invaluable diagnostic method for accessing cerebrospinal fluid and therapeutically treating elevated intracranial pressure. Although complications including hemorrhage and infection have been well documented, the formation of iatrogenic pseudoaneurysms following EVD placement has rarely been reported. The authors present a case of this exceedingly rare complication of iatrogenic pseudoaneurysm formation following EVD placement.

Coexisting sellar Rathke cleft cyst and planum sphenoidale meningioma: illustrative case.

Background: The co-occurrence of Rathke cleft cysts (RCCs) and meningiomas in the sellar and parasellar regions represents an exceedingly rare clinical entity. Achieving maximal resection through a single operative approach while minimizing adverse events is challenging, often necessitating multiple surgical approaches, as suggested by previous reports.

Observations: The authors report the case of a 49-year-old female with a history of kidney transplant who presented with headaches and was diagnosed with coexisting RCC and meningioma in the sellar and planum sphenoidale regions, respectively.

Background: Stereotactic radiosurgery (SRS) is a well-established option for the management of intracranial tumors, including meningiomas. Although valued for its low invasiveness and precision, it still carries a risk of complications. Communicating hydrocephalus is a serious, albeit rarely reported, complication of SRS.

Recurrent thrombus formation in a carotid web: highlighting the importance of timely surgical intervention. Illustrative case.

Background: Carotid webs are rare nonatherosclerotic disorders in the carotid artery and are increasingly recognized as factors of ischemic stroke in the young population. Asymptomatic webs can be treated with antithrombotic therapy, whereas symptomatic cases frequently require surgical interventions, including carotid endarterectomy (CEA). However, guidelines for the optimal timing of these treatments remain unestablished, especially compared to atherosclerotic stenotic lesions, due to the rarity of carotid webs.

Characterization of Chitinase 3-like protein 1 spatiotemporal distribution in human post-traumatic brain contusions and other neuropathological scenarios.

Chitinase 3-like protein 1 (CHI3L1) is emerging as a promising biomarker for assessing intracranial lesion burden and predicting prognosis in traumatic brain injury (TBI) patients. Following experimental TBI, Chi3l1 transcripts were detected in reactive astrocytes located within the pericontusional cortex. However, the cellular sources of CHI3L1 in response to hemorrhagic contusions in human brain remain unidentified.

The Impact of Electrophysiological Diversity on Pattern Completion in Lithium Nonresponsive Bipolar Disorder: A Computational Modeling Approach.

Introduction: Patients with bipolar disorder (BD) demonstrate episodic memory deficits, which may be hippocampal-dependent and may be attenuated in lithium responders. Induced pluripotent stem cell-derived CA3 pyramidal cell-like neurons show significant hyperexcitability in lithium-responsive BD patients, while lithium nonresponders show marked variance in hyperexcitability. We hypothesize that this variable excitability will impair episodic memory recall, as assessed by cued retrieval (pattern completion) within a computational model of the hippocampal CA3.

This study investigates the role of SNHG6 in SCI development and its underlying regulatory mechanisms.

Descriptive epidemiology and prognostic factors of atypical teratoid/rhabdoid tumors in the United States, 2001-2021.

Atypical teratoid rhabdoid tumor (AT/RT) is a rare embryonal central nervous system tumor with a dismal prognosis that occurs mostly in early childhood. Since recent epidemiological and prognostic information is limited, we aimed to describe and analyze AT/RT-related incidences, temporal trends and prognostic factors. Incidence and survival data between 2001 and 2021 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database.

The cortical high-flow sign in oligodendroglioma, IDH-mutant and 1p/19q-codeleted is correlated with histological cortical vascular density.

Background And Purpose: The cortical high-flow sign has been more commonly reported in oligodendroglioma, IDH-mutant and 1p/19q-codeleted (ODG IDHm-codel) compared to diffuse glioma with IDH-wildtype or astrocytoma, IDH-mutant. Besides tumor types, higher grades of glioma might also contribute to the cortical high flow. Therefore, we investigated whether the histological cortical vascular density or CNS WHO grade was associated with the cortical high-flow sign in patients with ODG IDHm-codel.

Pipeline embolization device for aneurysm recurrence after stent-assisted coiling.

Objective: Since the emergence of the Pipeline Embolization Device (PED), its off-label use has significantly improved the treatment effectiveness of complex intracranial aneurysms, including the treatment of recurrent aneurysms. Although PED is effective in this situation, there is still a lack of evidence-based medicine for its role in recurrent aneurysms after stent-assisted coiling. The aim of this study is to evaluate the safety and efficacy of PED treatment for recurrent aneurysms after stent-assisted coiling.

Nimodipine ameliorates subarachnoid hemorrhage-induced neuroinflammation and injury by protecting mitochondrial function and regulating autophagy.

Subarachnoid hemorrhage (SAH) is a type of hemorrhagic stroke, and the neuroprotective effects of nimodipine following SAH have been well-documented. Sirtuin 3 (SIRT3), a mitochondrial nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, plays a significant role in mitigating oxidative stress in various neurodegenerative conditions. However, the role of SIRT3 in the neuroprotective mechanisms of nimodipine after SAH remains unclear.
