Idiopathic Hypertrophic Pachymeningitis Mimicking Meningioma with Occlusion of Superior Sagittal Sinus: Case Report and Review of Literature.
Idiopathic hypertrophic pachymeningitis is a rare inflammatory condition with diffuse thickening of the dura mater, which may cause a compressive effect or vascular compromise. ⋯ Idiopathic hypertrophic pachymeningitis should be part of the differential diagnosis of some cases of meningioma.

Evidence continues to emerge regarding the inverse relationship between high neurointerventional case volume and complication rates, leading several medical/surgical societies to recommend minimum volumes for specific procedures. Recent data suggest few centers are meeting these requirements. We report a single center's neurointerventional complication rates with associated case volumes, along with a review of the literature. ⋯ We provided a single-center experience of the relationship between neurointerventional procedural case volume and complication rates in the growth phase of our center's establishment. We demonstrated that as our center was being developed, specific procedural staffing measures allowed proficiency maintenance, acquisition of new techniques, and complication avoidance, whereas specific case volumes crossed the suggested thresholds as defined in the literature.

Review Case Reports
Bilateral Recurrent Dysplastic Cerebellar Gangliocytoma (Lhermitte Duclos Disease) in Cowden Syndrome: A Case Report and Literature Review.
Dysplastic gangliocytoma (Lhermitte-Duclos disease [LDD]) typically presents as a PTEN (phosphatase and tensin homolog)-positive, insidious unilateral mass of the cerebellar cortex. Patients can present with symptoms of increased intracranial pressure. Magnetic resonance imaging (MRI) will reveal a characteristic laminar/tigroid appearance. Surgical management has been superior to conservative measures for symptomatic lesions. The outcomes for bilateral craniotomy have not yet been described. ⋯ To the best of our knowledge, the present case is the first reported case of bilateral cerebellar hemisphere LDD ultimately managed by temporally dissociated bilateral surgical resections. Our patient was unique in that he had undergone surgery for resection of LDD, followed by a second surgery for contralateral progression 8 years later. The therapeutic options to prevent recurrence are limited, although temozolomide did seem to impede progression. Symptomatic patients will typically benefit most from surgical intervention. Given the strong association between adult LDD and Cowden syndrome, maintaining close follow-up care and possible surveillance imaging will be essential.

Review Case Reports
Resection of Pediatric Trigeminal Schwannoma Using Minimally Invasive Approach: Case Report, Literature Review, and Video Submission.
Trigeminal schwannomas are fifth cranial nerve tumors that originate from the nerve sheath. They rarely occur within the pediatric population and can cause dysfunction of the trigeminal nerve and surrounding structures. When patients become symptomatic, neurosurgeons should consider resection. ⋯ We present a rare case of pediatric trigeminal schwannoma type Mp treated surgically with a near-total resection via a novel mini-pterional approach and use of cranial nerve diffusion tensor imaging.

The neutrophil-to-lymphocyte ratio (NLR) reflects the balance between innate and adaptive inflammatory responses. This study intended to evaluate parameters associated with admission high NLR and its impact on clinical outcome in patients with primary intraventricular hemorrhage (PIVH). ⋯ NLR tended to be associated with 90-day clinical outcomes of patients with PIVH and exhibited independent predictive power for pneumonia in PIVH.
