  • High Myopia-Sensorineural Deafness Syndrome

    Skiagrams of head, dorsolumbar spine, pelvis, both lower limbs and upper limbs revealed calvarial thickening, mild platyspondyly and outward bowing of radius and ulna.[indianpediatrics.net]

  • Osteopetrosis

    All cases of calvarial thickening in ADOP II were rated as moderate. Calvarial thickening was rated as mild in five of seven cases of IOP, and as moderate in two.[ajnr.org] Radiological features of both the siblings revealed calvarial thickening with diffused increase in density of the bones with poor development of sinuses (Fig. 1 a, b).[bmcresnotes.biomedcentral.com] (a) Lateral radiograph of the skull shows diffuse sclerosis and calvarial thickening.[pubs.rsna.org]
