Crossed Plagiocephaly (Differential Diagnosis Congenital Muscular Torticollis)

View from the top of the head of an infant in whom the front is slightly, the backhead more flattened. Both sternocleidomastoid muscles are normal. In this case of a crossed plagiocephaly neither a congenital muscular torticollis nor a hypertrophic sternocleidomastoid muscle is the cause of bilateral flattening. It is a positional plagiocephaly with another cause.
