Trauma-induced Acute Epidural Hematoma: The Rising Sun in a Progressively Lethargic Man

A young adult, 18 years of age, presented to the emergency department with severe traumatic brain injury (TBI) resulting from a bicycle versus vehicle head-on collision. The patient initially presented in a promising condition but quickly deteriorated into a state of unconsciousness with no meaningful responses to stimuli or coordinated voluntary movement. Stat computed tomography (CT) revealed a large, right-sided, acute epidural hematoma (EDH) with mass-effect and a severe midline shift indicative of immediate surgery. This case highlights the importance of closely monitoring traumatic brain injury patients regardless of initial presentation and neurological exam results, as the patient's condition may drastically and rapidly change without much warning. Additionally, it is key to utilize regular radiological studies on these patients, to detect any neurological changes as close to onset as possible. Lastly, it is imperative that neurosurgeons closely monitor the patients/ state of consciousness as a rapid decline serves as a key diagnostic indicator of the need for immediate surgery.
