The traditional management of pregnant patients with Chiari I malformation (CM-I) heavily favors cesarean section and general anesthesia to limit the perceived risk of maternal neurological complications attributed to vaginal delivery and neuraxial anesthesia. The aim of this study was to compare reported neurological symptoms and radiographic presentations before and after childbirth performed by patients with CM-I, with and without associated syrinx. ⋯ Our findings suggest that patients with CM-I may deliver vaginally and receive neuraxial anesthesia with low risk of neurological complications or radiographic worsening. As these patients were not prospectively selected, limitations exist, and it remains important to consider the severity of the patient's clinical and radiographic presentation when selecting anesthetic and delivery modality.

Identifying patients with basal ganglia intracranial hemorrhage (ICH) at risk of hematoma expansion (HE) may better define selection criteria for early surgical evacuation. The aim of this study was to use automated radiographic feature extraction to improve risk stratification for basal ganglia ICH expansion. ⋯ nv-CTD is a measure of bgICH acuity and can augment spot-sign bgICH expansion risk stratification.

Aggressive resection for primary tumors of the spine are associated with a high rate of adverse events (AEs), but the impact of AEs on patient-reported outcomes (PROs) remains unknown and is critical to the shared decision-making. Our primary objective was to assess the impact of surgical AEs on PROs using an international registry. Assessing the impact on clinical outcomes and identifying risk factors for AEs were our secondary objectives. ⋯ The rate of surgical AEs is considerable in this population. Surgical AEs seem to be associated with a higher number of readmissions, but do not seem to result in significant differences in PROs or in a higher risk of reoperation, mortality, and failure to achieve preplanned margins.

Magnetic resonance-guided focused ultrasound (MRgFUS) has been increasingly performed in recent years as a minimally invasive treatment of essential tremor and tremor-dominant Parkinson disease. One of the side effects after treatment is dysgeusia. Some centers use tractography to facilitate the treatment planning. However, there have been no reports of identifying gustatory tracts so far. Our aim was to investigate the technical feasibility of isolating and visualizing the gustatory tracts, as well as to explore the relationship between the gustatory tract and the MRgFUS lesion using actual patient data. ⋯ The thalamic gustatory tracts can be reliably visualized using tractography.
