BACKGROUND: Subgaleal hematoma (SGH) is defined as hemorrhage within the potential space between the galea aponeurotica and the periosteum. While SGH is well recognized in the neonatal period, its occurrence beyond infancy is rare, and chronic or progressively enlarging SGH in adolescents is exceedingly uncommon.
CASE DESCRIPTION: We report a 16-year-old male with severe autism spectrum disorder (ASD) and longstanding repetitive self-injurious head-banging behavior who presented with a massive, progressively enlarging scalp swelling. Neuroimaging demonstrated a large extracranial collection confined to the subgaleal space, with mixed radiological characteristics consistent with acute, subacute, and chronic hemorrhage, and no associated intracranial pathology. Surgical exploration revealed a giant mixed-stage SGH associated with markedly hypertrophied scalp vessels. Complete evacuation, meticulous hemostasis with selective vessel ligation, dead-space reduction, and subgaleal drainage were performed, resulting in excellent clinical and cosmetic outcomes without recurrence.
CONCLUSION: Repetitive self-injurious head trauma represents a rare but important etiology of giant chronic SGH in adolescents with severe ASD. Awareness of this mechanism is essential, as delayed recognition may lead to progressive enlargement and significant deformity. Timely surgical intervention can provide definitive management and durable resolution.
