Traumatic Parafalcine Subdural Hematoma: A Clinically Benign Finding

Abstract Background Guidelines for management of intracranial hemorrhage do not account for bleed location. We hypothesize that parafalcine subdural hematoma (SDH), as compared to convexity SDH, is a distinct clinical entity and these patients do not benefit from critical care monitoring or repeat imaging. Methods We identified patients presenting to a single level I trauma center with isolated head injuries from February 2016 to August 2017. We identified 88 patients with isolated blunt traumatic parafalcine SDH and 228 with convexity SDH. Results Demographics, comorbidities, and use of antiplatelet and anticoagulant agents were similar between the groups. As compared to patients with convexity SDH, patients with parafalcine SDH had a significantly lower incidence of radiographic progression, and had no cases of neurologic deterioration, neurosurgical intervention, or mortality (all P  Conclusions Patients presenting with a parafalcine SDH are a distinct and relatively benign clinical entity as compared to convexity SDH and do not benefit from repeat imaging or intensive care unit admission.
