Vessel wall magnetic resonance imaging (MRI) has been suggested as a potential in vivo method to detect inflammation of aneurysm wall and identify unruptured intracranial aneurysm (UIA) at high risk for rupture. This study aims to investigate the correlation between aneurysm wall enhancement (AWE) on vessel wall MRI and rupture-related morphological parameters in patients with multiple UIAs. ⋯ The presence of AWE on vessel wall MRI was significantly correlated with conventional morphological rupture risk factors in patients with multiple UIAs, which might indicate AWE as a potential radiologic predictor for UIAs with high rupture risk.

Transarticular screw fixation has fatal complications such as vertebral artery (VA), carotid artery, and spinal cord injuries. The landmarks for deciding the entry point for C1 lateral mass screws were clarified by using life-size 3-dimensional (3D) patient-specific spine models. ⋯ 3D models were used in surgical planning maximizing the possibility of ideal screw position and providing individualized information concerning cervical spinal anatomy. The individualized 3D printing screw insertion template was user-friendly, of moderate cost, and it enabled a radiation-free cervical screw insertion.

The aim of the study is to discuss along with literature knowledge the post-traumatic clinical progression of cases with symptoms of transient spinal cord impact and cases of spinal concussion following exposure of the vertebral column to vertical forces. ⋯ As a result of the vertebral column being affected by vertical forces, the most frequently affected are the thoracic segments of the spinal cord. These cases show similarities to real spinal cord injury without radiographic abnormality cases when evaluated along with clinical and radiologic symptoms. Absolute differential diagnosis from real spinal cord injury without radiographic abnormality cases cannot be made until total neurologic recovery takes place.

Intracerebral hemorrhage continues to be a major global problem. No standard treatment or surgical procedure has been identified for intracerebral hemorrhages. High morbidity and mortality rates caused by conventional approaches and the disease itself have necessitated more-invasive treatment methods. The endoscopic approach is a more minimally invasive method than craniotomy, which is another alternative surgical treatment. ⋯ Minimally invasive endoscopic hematoma evacuation may be a good alternative surgical method for treating supratentorial spontaneous cerebral hematomas.

Skull base surgeons split the tentorium to expand exposure, minimize brain retraction, and combine the supratentorial and infratentorial compartments for resection of large skull base lesions. The aim of this study was to describe stepwise techniques for splitting the tentorium to access deeply located skull base lesions and morphometrically assess gained exposure. ⋯ With splitting of the tentorium, a substantial area of expansion is obtained, minimizing the need for brain retraction and improving visualization of deep neurovascular structures in the skull base.
