Purpose: Hypofractionated short-course radiation therapy (SCRT) is an alternative treatment option for elderly or frail patients with newly diagnosed glioblastoma (GBM) post-surgery. This study compares survival outcomes and treatment costs between patients receiving SCRT and those undergoing standard long-course radiation therapy (LCRT).
Methods: This retrospective study utilized health insurance claims and national cancer registry data from Korea to compare overall survival (OS) and treatment costs between patients receiving SCRT and LCRT across all ages and sub-group analysis within the subgroup of cases aged 65 and older from 2016 onwards, a period when intensity-modulated radiotherapy (IMRT) was widely adopted.

Objective: Microscopic microvascular decompression (MVD) has been considered to be a useful treatment modality for medically refractory hemifacial spasm (HFS) and trigeminal neuralgia. But, the advent of the endoscopic era has presented new possibilities to MVD surgery. While the microscope remains a valuable tool, the endoscope offers several advantages with comparable clinical outcomes.

Objective: A stretched coil, characterized by excessive elongation within the parent artery during a coil embolization procedure, poses a significant risk of forming a thrombus. This study reports on cases of stretched coils spanning 16 years and discusses effective assessment methods and treatment strategies.
Method: Retrospective analysis of the institutional database comprising 14 cases where stretched coils were observed during coil embolization procedures was conducted, starting from January 2007.
A standardized protocol for the isolation of cell-free DNA (cfDNA) from cerebrospinal fluid (CSF) is lacking. Therefore, we established a cfDNA isolation protocol optimized for clinical CSF specimens, integrating acceptable modifications and using artificial CSF generated from remnant CSF spiked with reference cell-free tumor DNA (ctDNA). We compared the isolation yields of diagnostic (IVD)-certified column-based (CB) and magnetic bead-based (MB) isolation.

Methods: We retrospectively analyzed 313 CAS cases from January 2007 to December 2020, including 206 (66%) symptomatic and 107 (34%) asymptomatic cases.

Cranioplasty-related reperfusion injury has rarely been reported. Although there are several hypotheses, particularly regarding the mechanisms of the event, clear evidence is lacking. Here, we report the case of an 84-year-old man with traumatic intracranial hemorrhage and subdural hematoma who underwent decompressive craniectomy and hematoma evacuation in the right hemisphere.

The objective of this study is to report two rare cases of pituitary adenoma with spontaneous CSF rhinorrhea successfully operated by endoscopic transsphenoidal approach with vascularized nasoseptal flap (NSF).
Case Description: A 70-year-old woman presented with a 6-month history of watery rhinorrhea and posterior nasal drip that worsened when her head leaning forward.

Objective: Traumatic intracranial hematomas have been rarely evacuated by endoscopic surgery. The frontal lobe is the usual location for the traumatic intracerebral hematoma (TICH). Endoscopic evacuation for the frontal TICHs via an eyebrow incision is to be presented as minimally invasive surgery.

Computed tomography (CT) and magnetic resonance imaging (MRI) are the most preferred diagnostic modalities for CSDH assessment. With early diagnosis and adequate management, CSDH may show favorable prognosis in majority of the patients; however, recurrence after surgery can occur in a significant number of patients.

This study aimed to investigate the efficacy of IVT in AIS using propensity score matching, to determine whether IVT could reduce short- and long-term mortality, and to identify risk factors influencing short- and long-term mortality in AIS.During 2013 to 2014, the nationwide Korea Acute Stroke Assessment registry enrolled 14,394 patients with first-ever recorded ischemic stroke.
