Article Synopsis
- Neuroendovascular procedures require careful monitoring to prevent complications from unintended device movements, and AI advancements now allow for real-time notifications about these movements.
- In a study involving nine patients, a real-time AI software was used during coil embolization to provide notifications for key device actions, with promising results in terms of accuracy and safety.
- The AI system showed high precision and recall in detecting device movements, effectively aiding in the procedure without any reported adverse events, indicating its potential for future use in neuroendovascular therapies.
[Comparison of Bayesian Estimation and SVD Methods for CT Perfusion in Patients with Acute Stroke].

Article Synopsis
- The study compares Bayesian estimation algorithms with singular value decomposition (SVD) in analyzing CT perfusion (CTP) data from patients with acute cerebral infarction.
- CTP data from 13 patients were used to assess visual clarity of ischemic areas and calculate ratios between healthy and affected brain regions using both methods.
- Results indicated that Bayesian estimation outperformed SVD, particularly in measuring cerebral blood flow (CBF) and mean transit time (MTT), making it more useful for evaluating acute stroke patients.
Objective: This report highlights a case of a de novo aneurysm assumed to be caused by hemodynamic stress resulting from proximal basilar artery stenosis.
Case Presentation: A 76-year-old woman presented at our hospital with tinnitus. Although MRI did not reveal the cause of her tinnitus, it did uncover an incidental finding of basilar artery stenosis.
Objective: Subarachnoid hemorrhage due to ruptured vertebral artery dissecting aneurysm (rVADA) is associated with a high frequency of acute rebleeding and requires early treatment following onset. Parent artery occlusion (PAO) or stent-assisted coiling (SAC) embolization is selected as a treatment option according to the individual patient condition. This report is a retrospective examination evaluating the treatment outcomes for rVADA.

Case Presentation: A 70-year-old man developed dysarthria and left-sided sensory impairment and was then diagnosed with acute basilar artery occlusion. Mechanical thrombectomy was performed using a 6-Fr guiding sheath via the left vertebral artery (VA).
Cryptococcosis is a fungal infection that mainly occurs in immunocompromised patients. We present the first case of cryptococcal meningitis in a patient who was being administered everolimus for breast cancer. Everolimus, a selective inhibitor of mammalian target of rapamycin, is a molecular targeting agent that is administered not only as an immunosuppressive agent, but also as an anticancer therapeutic.

Here we describe a case of CSPS and propose a definition and classification for previously reported cases.
Case Description: A 54-year-old man presented with hypacusis and abducens nerve palsy.
