    Abstract Intradural extramedullary metastasis of renal cell carcinoma is exceedingly uncommon, and only 19 cases have been reported in the literature. It is thought to metastasize from the kidneys through venous networks or along nerves and may also spread from brain metastases through cerebrospinal fluid. We present a 52-year-old female, two years after a nephrectomy with myelopathic symptoms, who was found to have thoracic intradural extramedullary metastasis from renal cell carcinoma. The thoracic tumor was resected without any added deficit, but an additional brain mass was found on postoperative imaging. The present case and a literature review were discussed to explore considerations for neurosurgical intervention in similar patients, evaluate surgical outcomes, and highlight current theories on routes of metastasis. Given the risk of neurological decline in patients with metastatic intradural renal cell carcinoma, surgical resection should be considered upon its discovery, and postoperative surveillance imaging is encouraged.

    Abstract Intramedullary tumors of the spinal cord account for 2%-4% of all central nervous system tumors. Surgical resection with intraoperative neuromonitoring, although challenging, remains the mainstay of treatment with the goal to prevent neurologic decline. We present a case of an unusual anaplastic glioma of the thoracic spinal cord in a 42-year-old male that spanned 7 vertebral levels and could not be definitively characterized using the 2021 World Health Organization Classification of Central Nervous System Tumors.

    Abstract Introduction: There is a clinical equipoise between burr hole drainage (BHD) or twist drill craniotomy (TDC) as initial surgical intervention in patients with chronic subdural hematoma (cSDH). Moreover, the impact of type of postoperative drainage is not well elucidated. We performed a systematic review and meta-analysis comparing outcomes following BHD and TDC for initial surgical management in cSDH and to understand the impact of negative suction drainage with TDC.
    Methods: A literature search was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for studies that directly compared TDC and BHD. The following outcomes were compared between TDC and BHD: mortality, recurrence, reoperations, complications, and cure rates. Subgroup analysis was performed to determine impact of negative suction drainage with TDC.
    Results: Sixteen articles (n = 1,235; TDC: 663; BHD: 591) met inclusion criteria. Although complications (OR: 0.68, 95% CI: 0.38-1.23, p = 0.21; I
    Conclusion: A systematic review and meta-analysis of available literature directly comparing TDC and BHD for primary evacuation of cSDH did not demonstrate clear superiority of either technique, although reoperations may be higher following TDC. Use of negative suction drainage with TDC may lead to similar rates of reoperation as BHD.

    Abstract Introduction: Intracranial cavernous malformations (CMs) are rare vascular malformations of the central nervous system in children. Infantile patients, being a developmentally vulnerable age group, pose a special challenge for management of these lesions. We pooled data from infantile patients diagnosed at our institution and individual cases published in the literature to provide input towards therapeutic decision-making.
    Methods: A systematic search of PubMed, MEDLINE, Embase, and Scopus was performed in accordance with PRISMA guidelines to identify all reported cases of intracranial CMs in the literature for infantile patients aged ≤ 2 years. In addition, cases from our institution diagnosed between 2010 and 2020 were also included. Individual cases were pooled and analyzed for clinical presentation, natural history, and outcomes from conservative and surgical management.
    Results: A total of 36 cases were included, of which 32 were identified from the literature. Median age at presentation was 14 months (range: 2 days to 24 months) months; 53% (n = 19) were females. Most cavernomas (64%, 23/36) were supratentorial, while 30% (n = 11) were located in brainstem and 5.5% (n = 2) in the cerebellum. With the exception of one patient, all cases were reported to be symptomatic; seizures (n = 15/31, 48.3%) and motor deficits (n = 13/31, 42%) were the most common symptom modalities. A total of 13 patients were managed conservatively upon initial presentation. No symptomatic hemorrhages were observed during 26 total person-years of follow-up. A total of 77% (28/36) underwent surgery; either upfront (23/28, 82%) at initial presentation or following conservative management. Among 12 patients who had preoperative seizures, 11/12 (91.6%) achieved seizure freedom post-resection. Among 7 patients who presented with hemiparesis preoperatively, 5 (71%) demonstrated some improvement, while 1 remained unchanged, and another patient with a brainstem cavernous malformation had worsening of motor function postoperatively. Postoperative recurrence was noted in 3 cases (3/27, 11%).
    Conclusion: Annual risk of repeat hemorrhage may be low for infantile patients with intracranial cavernous malformations; however, better follow-up rates and higher number of cases are needed to make a definitive assertion. Surgical resection may be associated with high rates of epilepsy cure and provide improvement in neurological function in a select number of cases.

    Abstract Background: Superficial siderosis of the central nervous system is a rare syndrome notable for the presence of hemosiderin deposition due to chronic, repetitive hemorrhages into the subarachnoid space.
    Observations: The authors presented a case of superficial siderosis in a 14-year-old girl. It arose as a late postoperative complication after resection of a medulloblastoma. Despite the patient being asymptomatic, surveillance imaging demonstrated diffuse hemosiderin deposition within the cerebellar folia and cisternal segments of cranial nerves VII and VIII on gradient echo (GRE) sequences. Formal audiometric testing demonstrated bilateral loss of high-frequency tone recognition consistent with early sensorineural hearing loss. A pseudomeningocele due to multiple dural defects was identified as the likely cause, and definitive surgical repair was performed. Intraoperatively, the presence of blood-tinged cerebrospinal fluid confirmed a diagnosis of superficial siderosis.
    Lessons: This case highlighted the potential need to routinely include GRE or susceptibility-weighted sequences in postoperative surveillance imaging after resection of pediatric posterior fossa tumors.
