Occurrence without an obvious cause is uncommon. A 5-year-old girl presented with swelling in the left parietal region. Computed tomography revealed a subgaleal hematoma, which spontaneously disappeared within 28 days. This report describes a rare case of subgaleal hematoma without an obvious cause in a child beyond the neonatal period that resolved without invasive treatments like needle aspiration, drainage, and surgery. Clinicians should consider conservative treatment as an alternative to invasive procedures in such cases.en-USChildren beyond the neonatal periodComputed tomographyConservative treatmentParietal region swellingArticle
