They are generally seen in pediatric and young adult patients as supratentorial lesions with both solid and cystic components and have a high propensity for recurrence. APXAs occasionally demonstrate leptomeningeal dissemination (LMD) but very rarely at diagnosis.Observations: The authors describe the case of a 36-year-old male with a history of seizures and a known left temporal lesion since childhood, serially imaged and never biopsied, who presented with headache, increasingly frequent seizures, and right third nerve palsy. Imaging demonstrated significant interval enlargement of the lesion with intralesional hemorrhage and predominantly locoregional leptomeningeal enhancement. He underwent resection with gross-total resection achieved, and pathology revealed WHO grade 3 pleomorphic xanthoastrocytoma with ATG7::RAF1 fusion, 9p21 deletion, and telomerase reverse transcriptase promoter mutation, as identified by next-generation sequencing. This was followed by adjuvant whole-brain radiation therapy with boost and treatment with the MEK inhibitor cobimetinib.Lessons: APXA, an already exceedingly rare primary CNS tumor, can present unusually in older adult patients with concomitant LMD and cranial neuropathy. Advanced genomic profiling can tailor adjuvant therapy. https://thejns.org/doi/10.3171/CASE24768.","PeriodicalId":94098,"journal":{"name":"Journal of neurosurgery.

CT showed diffuse SAH and CT angiography revealed a 9-mm right internal carotid-ophthalmic artery aneurysm. On day 1, they performed balloon-assisted coil embolization. On day 8, MR angiography (MRA) showed severe CVS in both distal middle cerebral arteries. On day 15, MRA showed complete improvement of CVS. However, on day 21, MRA showed recurrence of diffuse CVSs, particularly in the right middle cerebral artery, right vertebral artery, and basilar artery, and CVS persisted for approximately 1 week. On day 29, an improvement in the CSV was observed on MRA, and subsequent monitoring revealed no further occurrence of CVS.Lessons: Here, a novel case of recurrence after complete improvement of CVS following aneurysmal SAH is presented.

The mechanisms underlying transformation remain poorly understood, with limited characterization of genetic changes associated with progression.Observations: A 55-year-old female presented with a large cerebellopontine angle EC with an enhancing nodule in the left tectum, for which she underwent resection. Three months following surgery, rapid enlargement of the residual tectal component required reoperation, with pathology showing SCC. Paired next-generation sequencing of the EC and SCC revealed multiple shared variants, including a pathogenic TP53 mutation. Additionally, the SCC contained a pathogenic PTEN variant absent in the EC, suggesting a second driver mutation contributing to malignant transformation of an EC (MTEC). Her SCC was resistant to volumetric modulated arc therapy, requiring subsequent chemotherapy and pembrolizumab combined with stereotactic radiosurgery. Despite a favorable initial response, she died 26 months following MTEC diagnosis.Lessons: To the authors' knowledge, this represents the first use of paired molecular profiling to link intracranial SCC to an EC precursor, enhancing precision of this rare diagnosis. Additionally, this case identifies specific genetic alterations associated with transformation, providing insight into the largely unknown mechanisms underlying MTEC. https://thejns.org/doi/10.3171/CASE24849.","PeriodicalId":94098,"journal":{"name":"Journal of neurosurgery.

MRI detected a heterogeneously enhancing mass in the pineal region. The patient underwent an endoscopic third ventriculostomy, and a biopsy sample was obtained. The pathology was initially consistent with a high-grade neuroepithelial tumor. Repeat imaging 3 weeks postoperatively demonstrated an interval increase in tumor size. He underwent a suboccipital craniectomy for gross-total resection. DNA methylation profiling was performed and was consistent with the diagnosis of HGAP.

The treatment strategy is often individualized based on the patient's disease characteristics.Observations: The authors report the case of a man who presented with an intraparenchymal hemorrhage. Cerebral angiography showed a typical MMD pattern characterized by occlusion and severe stenosis at the terminal portions of the bilateral internal carotid arteries, accompanied by moyamoya-like vasodilation. The bilateral posterior cerebral arteries (PCAs) had collateral blood supply to the anterior circulation, and 5 aneurysms were observed, which is rare. Considering that revascularization through bypass surgery could alter the hemodynamic stresses associated with MMD, the authors performed bilateral extracranial-intracranial bypass surgeries to reconstruct the anterior circulation and reduce the blood flow burden on the vertebrobasilar system. Follow-up imaging demonstrated improved cerebral perfusion in both hemispheres. Importantly, 3 of the 5 aneurysms remained stable, 1 aneurysm had shrunk, and the other had completely resolved.Lessons: For stable patients with cerebral hemorrhage, CT angiography is recommended before treatment. In surgery of patients with MMD-associated hemorrhage, avoid using artificial dura mater as it can hinder external carotid circulation and complicate future bypass procedures. https://thejns.org/doi/10.3171/CASE24848.","PeriodicalId":94098,"journal":{"name":"Journal of neurosurgery.

CT revealed a left thalamic hemorrhage extending into the left lateral ventricle. MRI showed no bleeding sources, including AVMs. By the age of 3 years, the patient developed West syndrome and was administered multiple antiseizure medication. At 5 years of age, the patient experienced convulsive status epilepticus, primarily on the right side of his body. A focal impaired awareness seizure due to the previous hemorrhage was considered. The patient remained seizure free until 11 years of age, when generalized seizures developed. MRI revealed a left thalamic AVM classified as Spetzler-Martin grade IV. The patient has been scheduled to undergo stereotactic radiosurgery.Lessons: Pediatric AVMs can undergo dynamic changes, including enlargement and de novo formation, acquiring the pathological features of adult AVMs. AVMs should be considered as a potential source of neonatal intracranial hemorrhage, necessitating long-term follow-up. https://thejns.org/doi/10.3171/CASE25124.","PeriodicalId":94098,"journal":{"name":"Journal of neurosurgery.

One rare etiology is transient occlusion of the vertebral artery (VA) with head rotation due to an osteophyte, termed bow hunter's syndrome. The authors present the case of recurrent thromboembolic posterior strokes secondary to transient reopening of an osteophyte-occluded VA.Observations: A 71-year-old man presented with dizziness and visual changes with a history of prior cervical fusion and myocardial ischemia, controlled with Plavix and aspirin. CT angiography of the neck revealed osteophyte occlusion of the right VA at C4, and MRI revealed a right posterior cerebral artery (PCA) infarct. The patient was discharged on Plavix and aspirin but returned 5 months later with worsening dizziness and visual changes. MRI revealed a new left PCA infarct, leading to repeat angiography. Movement of the head during the procedure recanalized the occluded VA from before. This prompted a diagnosis of thromboembolic stroke resulting from the reopening of the occluded VA with various head movements.Lessons: This case demonstrates the utility of dynamic cerebral angiography due to the ability to manipulate head position while visualizing blood flow. Despite the invasive nature of the procedure, it helped improve diagnostic accuracy and identify a rare vascular lesion. https://thejns.org/doi/10.3171/CASE25133.","PeriodicalId":94098,"journal":{"name":"Journal of neurosurgery.
