There is minimal information on COVID-19 pandemic’s national impact on pediatric neurosurgical operative volumes. In this study, using a national database, TriNetX, we compared the overall and seasonal trends of pediatric neurosurgical procedure volumes in the United States during the pandemic to pre-pandemic periods. In the United States, the incidence of COVID-19 began to rise in September 2020 and reached its maximum peak between December 2020 and January 2021. During this time, there was an inverse relationship between pediatric neurosurgical operative volumes and the incidence of COVID-19 cases. From March 2020 to May 2021, there was a significant decrease in the number of pediatric shunt (-11.7% mean change, p = 0.006), epilepsy (-16.6%, p < 0.001), and neurosurgical trauma (-13.8%, p < 0.001) surgeries compared to pre-pandemic years. The seasonal analysis also yielded a broad decrease in most subcategories in spring 2020 with significant decreases in pediatric spine, epilepsy, and trauma cases. To the best of our knowledge, this is the first study to report a national decline in pediatric shunt, epilepsy, and neurosurgical trauma operative volumes during the pandemic. This could be due to fear-related changes in health-seeking behavior as well as underdiagnosis during the COVID-19 pandemic.

Multinodular and vacuolating neuronal tumor (MVNT) is a rare benign brain lesion, commonly found in middle-aged adults. The patients experience a range of symptoms from being asymptomatic to epileptic seizures, with headache being the most common symptom. Here we report a case of an incidental diagnosis of MVNT in a young female. A 25-year-old female with a past medical history of occasional headaches without seizures or any focal neurological deficit presented after a motor vehicle rollover. The MRI brain revealed an incidental finding of a subcortical lesion in the right parietal lobe with T2-FLAIR (fluid-attenuated inversion recovery) hyperintensity between the cystic portions, indicative of a possible MVNT, with a less probable chance of dysembryoplastic neuroepithelial tumor based on the subcortical location of the lesion. No neurosurgical intervention was recommended. With one-year follow-up, no changes were noted on neuroimaging, and the patient remained stable without any neurological symptoms. The MVNT is a rare brain lesion that presents with benign features. In patients with epileptic symptoms, surgical resection of the lesion can be curative. However, in asymptomatic patients, careful monitoring may be sufficient, as described in this case.

Bell’s palsy is a relatively rare neurologic disorder with a limited selection of helpful therapies. This case report describes the author’s initial three-month experience living with severe Bell’s palsy, including a detailed history and timeline of the initial development of symptoms, treatments pursued, and psychological stress during the disease progression. A particular focus is placed on the emotional burden Bell’s palsy can have, exploring possible avenues to improve physician to patient education on mental health and well-being during initial and delayed recovery.

Although pleomorphic xanthoastrocytomas generally carry a fair prognosis, anaplastic transformation has been identified in a subset of cases.We present the case of a patient with primary anaplastic pleomorphic xanthoastrocytoma (APXA) that demonstrated rapid recurrence and diffuse leptomeningeal spread of disease three months postoperatively, causing severe visual impairment and acute ischemic strokes leading to death.We believe this is the fastest reported time to leptomeningeal dissemination and death from the initial diagnosis. Through this case, we show how anaplastic features can have a highly variable biological effect on disease progression. We believe earlier craniospinal imaging at the time of APXA diagnosis should be pursued to manage disease progression more aggressively with currently recommended adjuvant therapies.

Background: The awake craniotomy (AC) procedure allows for safe and maximal resection of brain tumors from highly eloquent regions. However, geriatric patients are often viewed as poor candidates for AC due to age and medical comorbidities. Frailty assessments gauge physiological reserve for surgery and are valuable tools for preoperative decision-making. Here, we present a novel case illustrating how frailty scoring enabled an elderly but otherwise healthy female to undergo successful AC for tumor resection. Case Description: A 92-year-old right-handed female with history of hypertension and basal cell skin cancer presented with a 1-month history of progressive aphasia and was found to have a ring-enhancing left frontoparietal mass abutting the rolandic cortex concerning for malignant neoplasm. Frailty scoring with the recalibrated risk analysis index (RAI-C) tool revealed a score of 30 (of 81) indicating low surgical risk. The patient and family were counseled appropriately that, despite advanced chronological age, a low frailty score predicts favorable surgical outcomes. The patient underwent left-sided AC for resection of tumor and experienced immediate improvement of speech intraoperatively. After surgery, the patient was neurologically intact and had an unremarkable postoperative course with significant improvements from preoperatively baseline at follow-up. Conclusion: To the best of our knowledge, this case represents the oldest patient to undergo successful AC for brain tumor resection. Nonfrail patients over 90 years of age with the proper indications may tolerate cranial surgery. Frailty scoring is a powerful tool for preoperative risk assessment in the geriatric neurosurgery population.

Neurosurgery residents spend a significant amount of their time teaching patients, families, students, residents, and other health professionals. To help ensure competence in their residents’ teaching abilities, many specialties have established formal residents-as-teachers (RAT) curricula; however, such formalized curricula are often lacking in neurosurgery programs. The authors’ goal was to develop and implement a formal RAT curriculum, designed with neurosurgery residents’ other responsibilities in mind, to improve residents’ formal and informal teaching abilities. Here, the authors report on the design of a formalized teaching curriculum tailored for the needs of neurosurgical residents, with a focus on deliberate practice and minimal time needed for preparation. The curriculum, designed using Kern’s 6 steps of curriculum design as a framework, comprises 5 lecture series spread over 3 years, repeated twice through a resident’s training, with each lecture series outlined with its respective topics and objectives. Opportunities for observed teaching as well as informal and formal evaluation will be provided to residents. The program will be evaluated on a yearly basis using direct and anonymized resident feedback on the RAT curriculum. Measures of program success will also include pre- and postprogram medical student and peer evaluation of residents. These data will be used for continual improvement of the curriculum as it is implemented. Successes and shortcomings of this program will be disseminated by publication, presentations, and placement on the authors’ department website and social media. This paper may serve as a foundation for other neurosurgical programs to develop RAT curricula for greater enhancement of resident teaching abilities.

A surge in interest in cortical bone trajectory (CBT), first described by Santoni in 2009, may be a result of its numerous advantages, including reduced surgical incision length and lateral dissection, limited disruption of the facet joints, and decreased blood loss. In addition, CBT offers improved screw pullout strength and the ability to perform hybrid constructs with pedicle screws using minimally invasive approaches. However, one of the main limitations of the technique involves the small screw size, which limits the potential for long-segment constructs. We describe a technique involving a more in-line anatomical trajectory, allowing for larger screw diameters. A feasibility study using a cadaveric model was performed and evaluated. Moreover, a focused review of the literature on the use of CBT was performed. Screw entry points are located along the inferomedial aspect of the facet and angled superolaterally. The use of this technique allows for the placement of larger screws (4.5 to 6.5 mm diameter) without pedicle breaches along with the alignment of screw heads from L1 to S1. In addition, the technique can be performed using stereotactic navigation or fluoroscopy. A direct, more in-line technique allows for larger screws to be placed using CBT. This technique can be combined with minimally invasive approaches. The potential advantages of the CBT technique support its use as a probable alternative to traditional pedicle screw fixation techniques.
