Nontraumatic Spontaneous Chronic Subdural Hematoma with Mass Effect and Midline Shift in an Adolescent

Abstract Chronic subdural hematoma (CSDH) is predominantly a disease of the elderly; it rarely occurs in the pediatric and adolescent population. Nontraumatic CSDH in young individuals presents unique diagnostic and therapeutic challenges due to its rarity and atypical presentation. This is a case of a 16-year-old female who presented with headache, vomiting, and no history of trauma. Noncontrast computed tomography revealed a large chronic subdural hematoma causing midline effect. Laboratory investigations were within normal limits. The patient underwent craniotomy and showed complete recovery with no neurological deficits. She was enrolled in regular follow-up in the pediatric outpatient department.
