Background And Objectives: Transient neurological deficits (TNDs) in patients with chronic subdural hematoma (CSDH), such as fluctuating aphasia, hemiparesis, or sensory disturbances, present diagnostic and treatment challenges as their pathophysiology remains unclear. The aim of this study was to investigate the association between specific MRI findings and TNDs in patients with CSDH and explored their relationship through intraoperative observation.

Methods: We retrospectively evaluated 72 patients with CSDH who underwent preoperative MRI among 251 CSDH patients treated from January 2020 to December 2023.

Background: Valve-related haemolysis is a known complication following prosthetic valve surgery. Haemolysis after transcatheter aortic valve implantation (TAVI) has been reported in some studies, all of which were non-critical. Data related to haemolysis associated with new-generation balloon-expandable valve (BEV) are scarce.

Background: Early seizures after craniotomy are significant perioperative complications that can adversely impact patient outcomes. Despite current guidelines advising against the routine use of antiseizure drugs for seizure after craniotomy prevention due to limited efficacy data, many clinicians continue prescribing them. This discrepancy highlights the need for robust evidence to guide clinical practice.

Background: Isocitrate dehydrogenase-mutant astrocytoma without cyclin-dependent kinase inhibitor 2A/B (CDKN2A/B) homozygous deletion typically follows a slow clinical course. However, some cases show early progression on magnetic resonance imaging, and these characteristics remain under-reported. This study aimed to elucidate the characteristics of isocitrate dehydrogenase-mutant astrocytoma showing early progression on magnetic resonance imaging.
