Background: Since the first report of a rapidly resolved subdural hemorrhage (SDH) in 1986, few additional case reports have been presented in the literature.
Case Report: An 82-year-old female patient presented with a SDH over the left convexity. The SDH was removed via catheter drainage through a burr hole trephination. Post-operative computed tomography (CT) following 300 mL drainage from the chronic SDH demonstrated a newly developed SDH along the right convexity. A follow-up CT performed 2 hours later revealed an unexpected significant resolution of the acute SDH.
Conclusion: The spontaneous resolution of acute SDH is believed to result from redistribution by washout of the hematoma by cerebrospinal fluid dilution. However, its exact pathophysiology is not well understood. When surgical evacuation is considered in acute SDH, conservative management should also be considered because spontaneous resolution of hemorrhage remains a possibility.
