Congenital disorders of glycosylation type 1A associated with cerebral hemorrhagic infarction: illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, Hirosaki University Graduate School of Medicine, Hirosaki, Aomori, Japan.
Background: Cases of congenital disorders of glycosylation (CDGs) are rare, and the occurrence of hemorrhagic infarction is also rare. The etiology is unclear.
Observations: A 3-year-old Asian boy with CDG type 1A was hospitalized with pneumonia.
Peritumoral vessel characteristics on magnetic resonance venography reflect the sinus invasion status of para-sinus meningioma.
Quant Imaging Med Surg
December 2024
Department of Radiology, Huashan Hospital, Fudan University, Shanghai, China.
Background: Early recognition of sinus invasion for meningiomas matters the clinical intervention. Therefore, we retrospectively investigated the relationship between peritumoral vessel features on magnetic resonance venography (MRV) and sinus invasion status.
Methods: Images of phase contrast MRV (PC-MRV, n=46) and contrast-enhanced MRV (CE-MRV, n=39) were independently assessed by four experienced neuroradiologists, including the adjacent sinus status, the peritumoral vessel count and diameter-associated parameters.
Dural Venous Sinus Thrombosis: A Rare Cause of Intracranial Hemorrhage.
Cureus
November 2024
Radiology, AdventHealth Orlando, Orlando, USA.
Dural venous sinus thrombosis, a subset of cerebral venous thrombosis, is an important pathology due to its significant morbidity and mortality. This process has an annual incidence of three to five cases per million adults. Although copious predisposing factors exist, the core principles revolve around Virchow's triad: venous stasis, hypercoagulability, and vascular endothelial damage.

Magn Reson Imaging
December 2024
Department of Radiology, Hyogo Medical University, 1-1 Mukogawa-cho, Nishinomiya City, Hyogo Prefecture 663-8501, Japan.
Purpose: This study aimed to compare the suppression of arterial signal intensity between tracking and fixed saturation pulses in lower extremity magnetic resonance venography (MRV).
Methods: Forty patients with varicose veins who underwent 2D true fast imaging with steady-state free precession using tracking and fixed saturation pulses on MRV were included. A fixed saturation pulse was applied from April 2020 to May 2021, and a tracking saturation pulse was applied from June 2021 to July 2022.
Effectiveness of super-selective digital subtraction angiography and 3D rotational digital subtraction venography for a developmental venous anomaly with an arteriovenous malformation: A case report and literature review.
Surg Neurol Int
November 2024
Department of Neurosurgery, Hamamatsu University School of Medicine, Hamamatsu, Japan.
Background: Arteriovenous malformation (AVM) and developmental venous anomaly (DVA) rarely coexist. Developing a surgical strategy to treat this co-occurrence is difficult due to the unclear pathogenesis. We report the use of super-selective digital subtraction angiography (DSA) and Three-dimensional (3D) rotational digital subtraction venography (DSV) to develop a surgical strategy for complex AVM draining into a DVA.
