A case of an infant with an asymmetrical head is presented. On clinical assessment the patient displayed features of deformational plagiocephaly. With the aid of three‐dimensional CT imaging of the skull, a bipartite parietal bone was diagnosed. The prevalence and possible aetiology of a bipartite parietal bone is discussed as well as a brief overview of the common causes of plagiocephaly.
