Unilateral Coronal Synostosis (Differential Diagnosis Congenital Muscular Torticollis)

Figure scha_17a_n.jpg to scha_17c_n.jpg: Clinical findings and CT in a newborn with a seeming torticollis to the right. Figure scha_17a_n.jpg: More impressive is the asymmetry of the face with a left-sided hypoplasia and scoliosis of the vertical midline axis. Figure scha_17b_n.jpg: The view from the top shows an insufficient roof over the right bulbus. Figure scha_17c_n.jpg: The CT slice shows an exophthalmos of the patient's right side. The diagnosis is a right coronal synostosis. The observed facial asymmetry differs from the asymmetry in congenital muscular torticollis; in contrast to the latter the hypoplasia concerns not the involved but the contralateral side. Pathognomonic for the unilateral coronal synostosis is an insufficient roof over the bulbus or an exophthalmos, which is mainly in the view from the top or in the CT recognizable.
