Idiopathic spontaneous bilateral subdural hematoma in a 28-year-old male: A comprehensive literature review and case report

BACKGROUND: Subdural hematoma (SDH) is considered spontaneous in the absence of trauma history. It is a common presentation in the geriatric age group due to the many influential factors. Most cases have a known underlying etiology that explains the incidence, otherwise, they are considered idiopathic. We present a rare case report of idiopathic nontraumatic bilateral SDH with a literature review of similar cases. CASE DESCRIPTION: A 28-year-old fit individual presented to the Emergency Department with a chronic history of severe headache and neck pain, associated with behavioral changes in the last 2 days. He reported that his symptoms started after lifting a heavy object 2 months ago; however, they became worse after a neck chiropractor therapy session. He is not on any chronic medications, and there was a negative history of trauma, seizure, hematological diseases, family history of neurological conditions, smoking, alcohol, or drug abuse with an unremarkable systemic review. A brain computerized tomography (CT) showed bilateral SDHs, for which he underwent bilateral mini craniotomies and drainage. The symptoms improved after surgery and the follow-up brain CT showed no recurrence. CONCLUSION: Idiopathic spontaneous bilateral SDH in the adult age group is an extremely rare pathology and the literature review only revealed three similar cases. With the absence of any pathology that would explain the presentation after extensive investigations, we hypothesized that a sudden rise in vascular pressure was the underlying etiology, especially with the fact that the symptoms became unbearable after the neck chiropractor therapy session.
