Huge recurrent subperiosteal hematoma in a 9-year-old boy: case report with special reference to pathologic and anatomic studies.

INTRODUCTION: Huge subperiosteal hematomas extending beyond the cranial sutures are rare and clinically, their distinction from subgaleal hematomas may be difficult. CASE REPORT: We report a subperiosteal hematoma that involved the entire scalp including the orbit and recurred within 6 months. DISCUSSION: We discuss our neuroradiologic and histopathologic findings and our management strategy.
