Stroke endovascular thrombectomy related subarachnoid hyperdensity: incidence, predictive factors, and a proposed sub-classification
Itsekzon-Hayosh Z, Carpani F, Hendriks EJ, Schaafsma JD, Mosimann PJ, Agid R and Krings T
Subarachnoid hyperdensity (SAH) after endovascular thrombectomy is a well-known phenomenon. Nevertheless, the clinical significance and natural history of this phenomenon is not well described. In addition, we test previously postulated hypotheses of distal occlusions sites and antithrombotic use to SAH prevalence and extent.

Evaluating a clinically available artificial intelligence model for intracranial aneurysm detection: a multi-reader study and algorithmic audit
Hu B, He H, Shi Z, Wang L, Liu Q, Sun Z and Zhang L
We aimed to validate a clinically available artificial intelligence (AI) model to assist general radiologists in the detection of intracranial aneurysm (IA) in a multi-reader multi-case (MRMC) study, and to explore its performance in routine clinical settings.
Pipeline embolization device for aneurysm recurrence after stent-assisted coiling
Kong W, Liang S and Lv X
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.
Deep orbital puncture of the superior ophthalmic vein for embolization of indirect carotid-cavernous fistula: a case report, technical note and review of the current literature
Biondi Soares LG, Andreão FF, Pereira FS, Korotkov DS, Paleare LFF, García-Zapata LR and Barbosa LA
Carotid-cavernous fistulas (CCFs) are abnormal connections between the carotid artery and cavernous sinus, often causing ocular symptoms like chemosis, proptosis, and diplopia. Endovascular embolization is the preferred treatment, typically performed via the transfemoral transvenous route through the inferior petrosal sinus (IPS). However, we present a case and a systematic review of indirect CCF treated through deep orbital puncture of the superior ophthalmic vein (SOV) for embolization.
Microstructural abnormalities of the dentato-rubro-thalamo-cortical tract in tremor dominant Parkinson's disease and essential tremor plus syndrome
Prasad S, Rajan A, Bharath RD, Saini J and Pal PK
The dentato-rubro-thalamo-cortical tract (DRTC) is considered to play a crucial role across tremor disorders including tremor dominant Parkinson's disease (TDPD) and essential tremor plus (ETP). This study aims to comprehensively evaluate microstructural integrity of the DRTC using single-compartment, i.e., DTI, and multi-compartment, i.e., neurite orientation dispersion and distribution imaging (NODDI), and free water (FW) based analysis.
The cortical high-flow sign in oligodendroglioma, IDH-mutant and 1p/19q-codeleted is correlated with histological cortical vascular density
Yamashita K, Murayama R, Itoyama M, Kikuchi K, Kusunoki M, Kuga D, Hatae R, Fujioka Y, Otsuji R, Fujita N, Yoshimoto K, Ishigami K and Togao O
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.

Zhang F, Hu J, Xiao Z, Lin C, Huang Z, Wang N and Liu Y
Spastic paraplegia type 5 (SPG5) is a rare neurodegenerative disease diagnosed primarily through genetic testing.We identified a specific spinal cord sign on conventional MR imaging to help narrow the scope of genetic screening.
Increased parietal operculum functional connectivity following vestibular rehabilitation in benign paroxysmal positional vertigo patients with residual dizziness: a randomized controlled resting-state fMRI study
Chen Z, Liu Y, Sun Y, Wei X, Liu H, Lv Y, Shan J, Dong S, Xiao L and Rong L
Residual dizziness (RD) is common in patients with benign paroxysmal positional vertigo (BPPV) after successful canalith repositioning procedures. This study aimed to investigate the therapeutic effects of vestibular rehabilitation (VR) on BPPV patients experiencing RD, and to explore the impact of VR on functional connectivity (FC), specifically focusing on the bilateral parietal operculum (OP) cortex.
Machine learning-based assessment of morphometric abnormalities distinguishes bipolar disorder and major depressive disorder
He K, Zhang J, Huang Y, Mo X, Yu R, Min J, Zhu T, Ma Y, He X, Lv F, Zeng J, Li C, McNamara RK, Lei D and Liu M
Bipolar disorder (BD) and major depressive disorder (MDD) have overlapping clinical presentations which may make it difficult for clinicians to distinguish them potentially resulting in misdiagnosis. This study combined structural MRI and machine learning techniques to determine whether regional morphological differences could distinguish patients with BD and MDD.

High-resolution vessel wall MRI in Moyamoya disease: a systematic review and meta-analysis of diagnostic and prognostic applications
Shahabi M, Zareshahi N, Kiani I, Gouravani M, Beikmarzehei A, Farahmand Y, Ranjbar E, Tafazolimoghadam A, Parsaei M, Moghaddam HS and Spiotta AM
Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the narrowing of arteries at the brain's base. While cerebral angiography is the gold standard for diagnosis, high-resolution vessel wall magnetic resonance imaging (VW-MRI) has recently emerged as a non-invasive diagnostic tool. This systematic review aims to provide insights into the role of VW-MRI in enhancing the diagnosis and management of MMD.

Objective information about the central auditory pathways in vestibular schwannoma can guide strategies for hearing rehabilitation and prognostication. This study aims to generate this information using diffusion tensor imaging (DTI).
Retinoblastoma and beyond: pediatric orbital mass lesions
Rumboldt Z, Dodig D, Galluzzi P, Brumini I, Clarke R, Singh S and Rossi A
Various space occupying lesions can arise in the orbit, ranging from developmental anomalies to malignancies, and many of the diseases occurring in children are different from the pathologies in the adult population. As the clinical presentation is frequently nonspecific, radiologic evaluation is essential for lesion detection and characterization as well as patient management. While orbital masses may in some cases involve multiple compartments, a simple compartmental approach is the key for the diagnosis on imaging studies, and MRI is the modality of choice. This pictorial review presents the most common and characteristic non-emergent pediatric orbital lesions, stressing their MRI and CT appearances, including specific differentiating features. The lesions are subdivided into 4 compartments: intraocular, intraconal, extraconal, and orbital walls. Retinoblastoma, Coats disease and persistent fetal vasculature; optic pathway glioma and lymphovascular malformations; rhabdomyosarcoma, infantile hemangioma, neurofibroma and lymphoma; neuroblastoma, leukemia/myeloid sarcoma, Langerhans cell histiocytosis and dermoid are reviewed in their respective compartments.

Ribeiro LFS, de Freitas LR, Udoma-Udofa OC, Monteiro JDS, Silva YP and Fagundes W
Tirofiban has emerged as an adjunct therapy for acute ischemic stroke (AIS) patients undergoing endovascular treatment (EVT). However, its benefits for AIS patients with intracranial atherosclerotic disease (ICAD) remains unclear. This meta-analysis evaluates its efficacy and safety in ICAD-related AIS patients undergoing EVT.
