Minimally-invasive Parafascicular Surgical (MIPS) Approach for the Management of a Pediatric Third Ventricular Ependymoma: Case Report and Review of Literature.
Minimally invasive parafascicular surgery (MIPS) has evolved into a safe alternative to access deep-seated subcortical and intraventricular pathologies. We present a case of a port-mediated resection of a pediatric third ventricular tumor. ⋯ The patient improved from baseline, with no remaining visual deficits, headaches, or balance issues. Pathology reported a World Health Organization grade II tanycytic ependymoma. To our knowledge, few cases have reported the utilization of port-based MIPS in pediatric patients.

To evaluate the differences in surgical outcomes of patients with cervical spondylotic myelopathy with and without congenital cervical spinal stenosis (CCSS). ⋯ Postoperatively, compared with non-CCSS patients, patients with congenital cervical stenosis reported equal quality of life for all markers. Our findings suggest that in patients with CCSS and relatively mild symptoms of myelopathy, equal consideration should be given for surgical intervention. The findings of this study warrant further large-scale, multi-institutional investigation to further understand the generalizability of these surgical outcome results.

Epidermoids account for <1.5% of all intracranial tumors. Overall, the cerebellopontine angle has been the most commonly reported location. In the supratentorial compartment, epidermoids will usually be found in the suprasellar area, sylvian fissure, and intraventricular area. The interhemispheric fissure represents an extremely rare location for supratentorial epidermoids, with limited cases reported previously. Surgery of an interhemispheric epidermoid can be challenging because of its adherence to the anterior cerebral artery branches or the brain parenchyma itself. In the present study, we have reported the largest Series of interhemispheric epidermoid tumors to better understand the clinical behavior, radiological features, and surgical outcomes. ⋯ Interhemispheric epidermoids can often reach a large size with substantial lateral extension found at diagnosis. The position of the anterior cerebral Artery branches can help to differentiate interhemispheric epidermoids from radiologically similar corpus callosum, velum interpositum, and cavum septum pellucidum epidermoids. Complete surgical excision with minimal complications is feasible, with good long-term outcomes.

Multicenter Study
Intraoperative 3-Dimensional Rotational Angiography in Cerebrovascular Surgery: A Case Series.
Intraoperative imaging is critical in cerebrovascular surgery to assess the technical success of the operation. This case series aimed to evaluate the safety and efficacy of 3-dimensional rotational angiogram (3D-RA) in addition to 2-dimensional intraoperative angiography (2D-IOA) during cerebrovascular surgery in the hybrid operating room. ⋯ Using a combination of 3D-RA and 2D-IOA in the hybrid operating room may enhance the likelihood of achieving an optimal result when employing microsurgical cerebrovascular surgery and avoid unanticipated incomplete outcomes, complications, and returns to the operating room. Whereas the addition of 3D-RA elucidated residual aneurysm not otherwise visualized on the 2D-IOA, in other cerebrovascular procedures studied, there was no additional value of the 3D-RA over the 2D-IOA.

Treatment of unruptured intracranial arteriovenous malformations (AVMs) has become controversial since the ARUBA (A Randomized Trial of Unruptured Brain Arteriovenous Malformations) study was published in 2014. We sought to analyze changes in the demographics, clinical presentation, and treatment strategies in 2 patient cohorts from the same institution separated by 40 years. ⋯ Compared to 40 years ago, more patients are presenting with incidentally discovered intracranial AVMs and are undergoing interventional treatment. Better understanding of the natural history, developments in endovascular therapy, and stereotactic radiosurgery, as well as improvements in microsurgical techniques have led to a substantial increase in patients undergoing invasive treatment.
