Cranium 14 from SH site. (A) Frontal view, showing the left glenoid and mastoid regions well below those of the right side. (B) Left lateral view. Note the rounded profile, and the vertical forehead. (C) Superior view. The projection of the torus supraorbitalis can be clearly seen. (D) Inferior view, revealing the characteristic deformities of this craniosynostosis: The posterior part of the cranium is twisted to the left with respect to the sagittal plane; the left glenoid cavity is more anteriorly placed than the right one. (Scale bar, to 5 cm.)

Relevant features in Cranium 14. (A) Posterior view, showing the parallelogram profile and the ipsilateral occipito-mastoid bulge, both diagnostic features of the left lambdoid suture premature fusion. Note the deviation of the sagittal plane with respect to the sagittal suture plane, showing that the Inion, the occipital crest and other medial structures of the nuchal plane are positioned 10 mm or more to the left. From top to bottom, the white arrows mark the craniometric points Lambda, Inion, and left Asterion, respectively. Discontinuous lines show the displacement of the sagittal suture and the occipital midline. (Scale bar, 5 cm.) (B) Close-up of part of the left lambdoid synostosis. The section where the suture is almost completely obliterated is enhanced above. (Scale bar, 2 cm.) (C) Virtual endocast of Cranium 14, superior view. Upper arrows point to the bregmatic arachnoid granulations. Lower arrow points to the obelionic arachnoid granulation. (Scale bar, 5 cm.) (D) Cribra orbitalia on Cranium 14 right orbital roof. (Scale bar, 1 cm.)

Virtual endocast of Cranium 14. From top to bottom, left to right: frontal, posterior, superior, inferior, left lateral, and right lateral views. Note the general bilateral asymmetry, the occipitomastoid bulging of the left side, the anteriorly placed left temporal lobe compared with the right, and the protruding left occipital pole. (Scale bar, 10 cm.)

Diagnostic profiles of unilambdoid synostosis of Cranium 14. (A) Trapezoid-shape in vertex view. (B) Parallelogram profile in posterior view. (Scale bar, 5 cm.)
