The latest World Health Organization data showed that stroke was the highest mortality in China, accounting for 23.7% of the total mortality from 2000 to 2012. Intracerebral hemorrhage (ICH) was the most deadly and incurable type of stroke. In the Qinghai-Tibetan Plateau, the incidence of stroke was relatively higher. Several studies showed that the shape and heterogeneity of hematoma and image markers on brain computed tomography scan had predictive effects on hematoma expansion (HE). The study aimed to find relative factors and established a nomogram model to predict the HE of ICH. ⋯ This model had a high accuracy of predicting HE in the Qinghai-Tibetan Plateau. Because this model is noninvasive, rapid, and low cost, it is easy to promote and has wide application prospects in clinical practice.

Paroxysmal sympathetic hyperactivity (PSH) is an uncommon complication of severe traumatic brain injury (sTBI). The clinical risk factors for PSH have not been fully characterized, especially regarding tracheostomy, which has usually been recommended for patients with sTBI to facilitate treatment. We examined the effects of tracheostomy on PSH incidence in patients with sTBI. ⋯ Our results suggest that tracheostomy is independently associated with an increased incidence of PSH.

Isolated cervical pseudoaneurysms of the internal carotid artery (ICA) in patients with Marfan syndrome are extremely rare. ⋯ Pseudoaneurysms of the cervical ICA associated with Marfan syndrome are rare. Carotid test occlusion and endovascular permanent embolization are possible in a patient with life-threatening symptoms. Cautious use of vascular closure devices, especially collagen plug-based ones, are required in such patients, given their abnormal extracellular matrix structure.

To evaluate differences between thicknesses of the ligamentum flavum (LF) and diameter of the spinal canal in different neck positions in patients with ossification of the posterior longitudinal ligament (OPLL) and patients with cervical degenerative spondylosis (CDS) using cervical dynamic magnetic resonance imaging (MRI). ⋯ Dynamic morphometric changes were found to be significantly greater in the CDS group than in the OPLL group. The study shows dynamic MRI may provide additional information in CDS patients.

Differentiation of primary central nervous system lymphoma (PCNSL) from glioblastoma using arterial spin labeling perfusion and diffusion tensor imaging (DTI). ⋯ The noninvasive imaging parameters using TBF and DTI might help in differentiating PCNSL from glioblastoma.
