The present study described a modified technique of atlantoaxial arthrodesis in patients with atlantoaxial instability (AAI) along with the postoperative clinical and radiological results. ⋯ Modified atlantoaxial arthrodesis via intraarticular autografting using the structural iliac bone combined with posterior instrumentation appears to be an efficient alternative treatment method for AAI patients with concurrent pathologies, even when the C1-2 posterior arches are unavailable for the grafting bed.

Endoscopic ventricular surgery (EVS) shows overall reduced morbidity compared to open craniotomy, but carries, however, the risk for neurocognitive impairment caused by fornix-, hypothalamus-, and injuries other structures adjacent to the ventricular system. Objective or subjective neurocognitive impairment after EVS is rarely reported. The aim of this study was to assess the subjective neurocognitive outcome in patients undergoing EVS for various pathologies. ⋯ Subjective neurocognitive outcome and quality of life improvement are often achieved after EVS and permanent neurocognitive impairment is rare. Further well-designed trials on subjective and objective neurocognitive outcome after EVS are warranted.

Currently, there is a unanimous opinion that the first line of the treatment of insular gliomas is microsurgical removal.1-3 At the same time, surgery of insular glial tumors remains a challenge because of the complex anatomy of the insular region. Among the most crucial anatomical structures are branches of the middle cerebral artery (MCA), lenticulostriate arteries (LSAs), and corticospinal tract.4 Surgery of the insular glioma becomes much more complicated in cases when the tumor extends to the anterior perforated substance, which, according to our data, occurs in 29,1% of cases.5 We present a 33-year-old woman with a history of generalized seizures (Video1). ⋯ The video demonstrates the technique of a Sylvian fissure dissection, manipulations with MCA branches and LSA, removal of the tumor from the region of the anterior perforated substance, and a discussion of surgical nuances and safety aspects. The most challenging part of the operation was to identify and protect the LSAs.6 Advanced microsurgical techniques, and the correct patient selection for surgical treatment, are cornerstones for a successful outcome and provide an acceptable frequency of postoperative neurologic deficits in patients who undergo surgery of insular gliomas through the transsylvian approach.

Tectal plate tumors are a rare subset of midbrain tumors in pediatric populations. They are slow growing and low grade, with indolent and subtle manifestation unless they cause hydrocephalus.1-5 We present a tectal tumor in an 8-year-old girl (Video 1). Her clinical onset occurred with headache, vomiting, and seizure secondary to intracranial hypertension. ⋯ When this approach is selected, the venous anatomy must be navigated with caution. Angiography's venous phase may provide additional planning information.6 Coagulation of vascular structures such as occipital veins is carefully avoided since it creates risk of venous infarction, leading to visual loss. Histologic examination revealed a rosette-forming glioneuronal tumor (grade I WHO 20217).

Socioeconomic status and race have been found to influence patient outcomes for various cancer subtypes. In particular, minority and economically vulnerable patients present with more advanced disease and experience decreased survival compared to others. The aim of this study was to analyze the association between demographic or socioeconomic variables and rates of postsurgical follow-up after pituitary neuroendocrine tumor (PitNET) resection. ⋯ Black patients and those with high social vulnerability have decreased rates of follow-up after PitNET resection. Follow-up delays can lead to failed identification of tumor recurrence, potentially resulting in more advanced disease by the time medical care is reinitiated and increasing rates of patient morbidity and mortality. As a result, further work is needed to address and bridge these care gaps.
