Idiopathic spontaneous subacute subdural hematoma in a healthy young male: a case report.

Chronic and subacute subdural hematomas are a common pathology of the geriatric population. Idiopathic spontaneous chronic and subacute subdural hematoma are unusual, with only 22 reported cases in patients younger than 40 years old. We report in this article an unusual case of spontaneous subacute subdural hematoma in a 16-year-old healthy male presenting as a sudden onset of intracranial hypertension with an unremarkable physical and neurological examination. CT scan of the head confirmed the diagnosis, and the patient underwent surgical evacuation of the hematoma. Follow-up was unremarkable, and further blood tests were all within normal range. Sudden-onset intracranial hypertension in previously healthy patients should be further explored, and the possibility of a subdural hematoma should be considered in the differential diagnosis.
