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.
