Ossified Chronic Subdural Hematoma and Subsequent Epstein-Barr Virus-Positive Large B-cell Lymphoma: A Case Report and Literature Review.
Ossified chronic subdural hematoma (CSH) associated with neoplasm has rarely been reported in the literature. We describe a patient with ossified CSH and underlying large B-cell lymphoma and discuss the relationship between lymphoma and CSH, emphasizing clinical characteristics, tumorigenic mechanism, and histopathologic analysis. ⋯ Based on reported cases and relevant literature, large B-cell lymphoma may be associated with ossified CSH.

Review Case Reports
A Precursor to Multiloculated Hydrocephalus: Case report and Review of Literature.
Multiloculated hydrocephalus (MH) is a challenging pathology for pediatric neurosurgeons, arising from various etiologies including intraventricular hemorrhage, infection, and overshunting. Although previous publications have discussed the potential etiology of this pathological process, including fibroglial webbing, no clear precursor has been proven. We present a case of MH developing after both intraventricular hemorrhage and intraventricular infection, with visualization of the precursor via endoscopy and a confirmed glial scar on pathological examination. ⋯ MH is a complex pathology with multiple risk factors. To date, only theories regarding the etiology have been proposed. Our case represents the first known direct visualization of intraventricular fibroglial webbing with magnetic resonance imaging correlation. Improved understanding of the pathophysiology of this entity may improve our ability to treat this pathology before loculations develop.

Intracranial pressure (ICP)-guided therapy has been the mainstay of treatment of patients with severe traumatic brain injury (TBI), but recent data have questioned its efficacy. The aim of this study was to demonstrate trends in compliance to TBI guidelines and use of ICP-guided care in a mature trauma system. ⋯ As studies emerged that demonstrated unclear benefit of ICP monitoring in improving care in patients with severe TBI, there was a significant statewide decline in the use of ICP monitoring after 2014 among all TBI subpopulations despite noteworthy limitations in the aforementioned studies and clear recommendations from the Brain Trauma Foundation guidelines.

Thyrotropin (TSH)-secreting pituitary tumors are rare and typically present with hyperthyroidism. Here we report the diagnosis, treatment, and surgical outcomes in a series of patients with TSH-secreting pituitary tumors in a tertiary referral center. ⋯ Our results confirm the clinical and hormonal heterogeneity caused by TSH-secreting pituitary adenomas. Surgery is considered the first choice of treatment for these tumors. We observed surgical cure rates similar to those reported in recent published series. SSTR2 and SSTR3 are highly expressed in TSH-secreting pituitary adenomas. Our results suggest that somatostatin analog treatment may be also helpful in the treatment of TSH-secreting pituitary adenomas.

YouTube has rapidly become one of the most widely accessed educational platforms of our time. Over 1 billion hours of YouTube content are viewed every day, including neurosurgical videos. To date, there has never been a qualitative analysis of neurosurgical content on YouTube. ⋯ YouTube is a frequently viewed but biased source for neurosurgical information. Advertisements are frequently disguised as educational material, and few videos provide references or sources for their information.
