Creutzfeldt-Jakob Disease in a Saudi Female: A Case Report.

Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive, and incurable neurodegenerative disorder caused by prions. It is invariably fatal and classified under transmissible spongiform encephalopathies. This case report presents a 66-year-old Saudi female who was admitted to the neurology department due to a rapidly advancing cognitive decline.

Brain tissue integrity in neuromyelitis optica spectrum disorder through T1-w/T2-w ratio, MTR and DTI.

Background: The presence of diffuse brain damage in normal-appearing white matter (NAWM) and gray matter (NAGM) in neuromyelitis optica spectrum disorder (NMOSD) remains controversial. We aimed to address this controversy by applying a multiparametric MRI approach. Additionally, the association between MRI metrics and clinical variables was explored.

Temporal changes and implications of diffusion tensor imaging metrics and cerebral white matter volume in patients undergoing carotid endarterectomy - a prospective study.

Aims: To test utility of diffusion MRI-derived indices in carotid endarterectomy (CEA), change of diffusion tensor imaging (DTI) metrics, cerebral white matter (WM) volumes were evaluated and predictors of overall mortality determined.

Methods: Prospectively enrolled participants had preoperative, immediate and late postoperative DTI after CEA. WM volumes, DTI metrics (fractional anisotropy, FA; axial, radial, mean diffusivities; AD, RD, MD, respectively) were calculated for the index/contralateral hemispheres at all time points.

Borderline Findings in -(2-[F]-Fluoroethyl)-l-Tyrosine PET of Patients with Suspected Glioma Relapse: Role in Clinical Practice.

One of the most common clinical indications for amino acid PET using the tracer -(2-[F]-fluoroethyl)-l-tyrosine (F-FET) is the differentiation of tumor relapse from treatment-related changes in patients with gliomas. A subset of patients may present with an uptake of F-FET close to recommended threshold values. The goal of this study was to investigate the frequency of borderline cases and the role of quantitative F-FET PET parameters in this situation.

Multidisciplinary, multicenter consensus for the care of patients affected with Sturge-Weber syndrome.

Background: Sturge-Weber Syndrome (SWS) is a rare, sporadic neurocutaneous disorder affecting the skin, brain, and eyes, due to somatic activating mutations in GNAQ or, less commonly, GNA11 gene. It is characterized by at least two of the following features: a facial capillary malformation, leptomeningeal vascular malformation, and ocular involvement. The spectrum of clinical manifestations includes headache, seizures, stroke-like events, intellectual disability, glaucoma, facial asymmetry, gingival hyperplasia, etc.

The effects of admission hyperglycemia and diabetes mellitus on mechanical thrombectomy outcomes: A systematic review and meta-analysis.

Background: The impact of certain comorbidities on mechanical thrombectomy (MT) outcomes remains largely unexplored. Diabetes mellitus (DM) and admission hyperglycemia have been associated with poor clinical outcomes for patients treated with MT. In this study, we sought to investigate the effects of DM and admission hyperglycemia on MT outcomes.

The "CUPCAKE" technique (coiled underlying pseudoaneurysm contained by a woven endobridge device) for treating intracranial aneurysms with atypical morphology.

Background: Intrasaccular flow diversion using the woven endobridge device (WEB; MicroVention, Aliso Viejo, CA, USA) for the treatment of intracranial aneurysms has demonstrated large scale safety and efficacy. However, limitations arise from its structural configuration, restricting its application to specific aneurysm sizes and shapes.

Technique Overview: We introduce the CUPCAKE technique, a combination of conventional coiling followed by WEB intrasaccular flow disruption in select cases of atypical aneurysms with technically challenging morphology not typically treatable by WEB alone.

Middle meningeal artery embolization for recurrent subdural hematoma in an extra-intracranial anastomosis patient on anticoagulant medication: A case report.

Symptomatic chronic subdural hematoma (cSDH) is amongst the most frequent neurological diseases with an upward trend due to an aging society and development in the field of anticoagulation therapies. Lately, subgaleal drainages and middle meningeal artery (MMA) embolization have been introduced to the standard armamentarium as treatment options for cSDH patients. Vascular anomalies, such as internal carotid artery (ICA) occlusion with spontaneous extra-intracranial anastomoses, usually lead to forfeiting embolization treatment from patients.

Paramagnetic rim lesion formation is predicted by the initial gadolinium-enhancing lesion diameter.

Background: Paramagnetic rim lesions (PRLs) are a magnetic resonance imaging (MRI) marker of compartmentalized intraparenchymal inflammation.

Objectives: The primary objective was to investigate clinical, demographic, and MRI factors that may be predictive of the future formation of PRL.

Methods: This is a retrospective analysis of longitudinal data.

Intra-arterial lidocaine administration of lidocaine in middle meningeal artery for short-term treatment of subarachnoid hemorrhage-related headaches.

Background And Purpose: We report short- and intermediate-term effects on headaches with intra-arterial injection of lidocaine in the middle meningeal artery in patients with severe headaches associated with subarachnoid hemorrhage.

Methods: We treated seven patients with intra-arterial lidocaine in doses up to 50 mg in each middle meningeal artery via a microcatheter bilaterally (except in one patient). We recorded the maximum intensity of headache (graded by 11-point numeric rating scale) prior to procedure and every day for the next 10 days or discharge, whichever came first.

Comparative Effects of Glenzocimab and Eptifibatide on Bleeding Severity in 2 Mouse Models of Intracranial Hemorrhage.

Background: Antiplatelet drugs represent potential candidates for protecting the penumbral microcirculation during cerebral ischemia and improving the benefits of arterial recanalization in ischemic stroke. Yet while the efficacy of such adjuvant strategies has been shown to be highly time dependent, antiplatelet therapy at the acute phase of ischemic stroke cannot be envisioned until the diagnosis of stroke and its ischemic nature have been confirmed because of the presumed risk of worsening bleeding in case of intracranial hemorrhage (ICH). Here, we investigated this risk for 2 antiplatelet drugs currently being tested in clinical trials for ischemic stroke, glenzocimab and eptifibatide, in 2 mouse models of ICH.

Determinants of cerebrospinal fluid leakage in a large cohort of macroprolactinomas.

Background: Non-functional adrenal incidentaloma (NFAI) is associated with increased risk of adverse cardiometabolic outcome. Identifying predictors of atherosclerotic cardiovascular disease (ASCVD) may enable more appropriate management strategies in patients with NFAI. We aimed to investigate body composition parameters and ASCVD risk in patients with NFAI.

Prognostic Value of Signal Abnormalities on Brain MRI in Post-Anoxic Super-Refractory Status Epilepticus: A Single-Center Retrospective Study.

Background: Epileptiform activity, including status epilepticus (SE), occurs in up to one-third of comatose survivors of cardiac arrest and may predict poor outcome. The relationship between SE and hypoxic-ischemic brain injury (HIBI) is not established.

Methods: This is a single-center retrospective study on consecutive patients with post-anoxic super-refractory SE.

Ectopic Thyrotropin-Secreting Tumor in the Nasopharynx Causing Central Hyperthyroidism.

We report a 31-year-old man with diarrhea and tachycardia. Diagnostic workup confirmed raised free thyroid hormones with unsuppressed thyroid stimulating hormone (TSH). Laboratory assay and medication interference were excluded.

Methods: We performed a retrospective cohort study using the TriNetX database, covering data from 2009 to August 2024.

From skin to heart: The rare journey of pleomorphic dermal sarcoma metastasis.

Cardiac tumours can be classified as neoplastic or non-neoplastic, with secondary tumours being significantly more common than primary ones. Among secondary tumours, melanoma has the highest propensity for cardiac involvement. Pleomorphic dermal sarcoma (PDS) is a rare skin neoplasm, with an estimated metastatic risk of 10% to 20%.

A Rare Case of Ramsey Hunt Syndrome With Cranial Polyneuropathy: Findings of the Brain MRI.

In this case, we present the case of a 74-year-old female patient who visited the University Hospital of Patras, Greece, because of a 10-day history of earache and discharge in the left ear. Concurrently, the patient exhibited ipsilateral peripheral facial nerve palsy. We also observed vesicular eruption at the auricle and the external auditory canal (EAC) of the left ear.

Lumbopelvic hyperlordosis is linked to higher femoral head coverage, lower femoral anteversion and younger age at periacetabular osteotomy.

Purpose: The dynamic alignment of the lumbar spine, pelvis and femur is increasingly studied in hip preservation surgery. However, the interaction between lumbopelvic alignment, acetabular and femoral morphology and its influence on patients' preoperative symptom burden remains poorly understood. The aim of this study was to evaluate whether lumbopelvic malalignment affects osseous hip morphology and exacerbates preoperative patient-reported joint functionality in patients undergoing periacetabular osteotomy (PAO).

High-Field-Blinded Assessment of Portable Ultra-Low-Field Brain MRI for Multiple Sclerosis.

Background And Purpose: MRI is crucial for multiple sclerosis (MS), but the relative value of portable ultra-low field MRI (pULF-MRI), a technology that holds promise for extending access to MRI, is unknown. We assessed white matter lesion (WML) detection on pULF-MRI compared to high-field MRI (HF-MRI), focusing on blinded assessments, assessor self-training, and multiplanar acquisitions.

Methods: Fifty-five adults with MS underwent pULF-MRI following their HF-MRI.

Development and validation of a score for clinical deterioration in patients with cerebral venous thrombosis.

Patients with cerebral venous thrombosis (CVT) may experience poor response to anticoagulant therapy and delayed surgical treatment may lead to clinical deterioration. However, the factors contributing to clinical deterioration remain poorly understood. Patients with CVT from three centers between January 2017 and October 2023 were included and grouped as the development cohort and validation cohort.
