To prospectively evaluate the diagnostic value of 3.0 Tesla magnetic resonance 3-dimensional sampling perfection with application-optimized contrast using different flip angle evolution (3D-SPACE) in the detection of sinus wall invasion and sinus patency in parasinus meningiomas. ⋯ With an integrative presentation of parasinus meningioma, wall invasion, lumen patency, and collateral veins, high-resolution 3D-SPACE imaging provides a reliable technique to accurately assess venous sinus invasion preoperatively.

Electrocardiogram (ECG)-triggered angiography non-contrast-enhanced (TRANCE) imaging is useful for investigating peripheral vessel diseases; however, its efficacy for access route assessment in cerebral angiography has yet to be reported. Therefore we aimed to evaluate the efficacy of TRANCE imaging in the assessment of the access route before diagnostic subtraction angiography for cerebral vascular disorders. ⋯ TRANCE imaging before diagnostic angiography is useful because it allows detailed assessment of the access route. This practice may reduce procedure time, thus resulting in fewer complications.

Comparative Study
Comparative Analysis of Orbitozygomatic and Subtemporal Approaches to the Basilar Apex: A Cadaveric Study.
The subtemporal and orbitozygomatic approaches are the most commonly used surgical approaches for the treatment of basilar artery apex (BAX) aneurysms. Relative advantages and disadvantages are generally reported based on surgeons' experience. This study was performed to provide a detailed comparison between the subtemporal and orbitozygomatic approaches based on cadaveric dissection analysis for the treatment of BAX aneurysms. ⋯ The orbitozygomatic approach provides a greater number of surgical corridors to the BAX and is superior regarding multiple surgically relevant anatomic parameters. Importantly, control over the basilar trunk and over the contralateral SCA and PCA (blind spots) is superior with the orbitozygomatic approach.

The inflammatory response plays a vital role in the pathologic mechanism of intracerebral hemorrhage. It recently has been reported that neutrophil to lymphocyte ratio (NLR) could represent a novel composite inflammatory marker for predicting the prognosis of intracranial hemorrhage (ICH). However, in considering the effects of surgical evacuation on the initiation of inflammatory responses, the relationship between NLR and functional outcome of patients with ICH after surgical treatment is still controversial. Here, we aimed to assess the predictive value of admission NLR and other available laboratory parameters for 90-day outcome of patients with ICH undergoing neurosurgical treatment. ⋯ Other than the association of prognosis of patients with ICH, NLR exhibited potential independent predictive ability for 90-day functional outcomes of patients with ICH after surgery.

Case Reports
Demonstration of Infectious Transgression Through the Skull Base Occurring 9 Years After Pituitary Adenoma Resection.
Sellar infections represent less than 1% of all sellar lesions and can be life-threatening. These infections occur de novo in up to 70% of patients or can less commonly develop after surgical treatment of another primary lesion, such as a pituitary adenoma. ⋯ This case demonstrates the fact that patients with pituitary lesions who have foreign material used for surgical closure can present with infections many years after the initial intervention. Furthermore, with appropriate clinical diagnosis and treatment, the reactive inflammation caused by sellar infection is reversible. We review the literature regarding the risk factors and management strategies for delayed postoperative sellar infections.
