Partial or complete division of the parietal bones resulting in anomalous cranial sutures is a rare entity and may raise concern for fracture and potential abuse when identified on radiological examination in young children. We present a case of a 4-week-old male found to have anomalous intraparietal sutures originally interpreted as fractures during a comprehensive evaluation for nonaccidental trauma. Our goal is to raise awareness of a complex branching pattern of accessory intraparietal sutures, which has not been previously described. Additionally, we will review the characteristics that aid in the radiologic differentiation of accessory cranial sutures and fractures. (C) 2016 Elsevier Inc. All rights reserved.
