The so-called midline-malformations of the brain which include alterations of ventricles or arachnoid spaces formerly only were found by invasive procedures performed because of their various clinical signs. Since cranial computerized tomography is available, by this new noninvasive method all these disturbances can be diagnosed safely. ⋯ The persistent performed cavities especially the cavum septi pellucidi, the cavum Vergae and the cavum veli interpositi, additionally the agenesis of the corpus callosum, the Dandy-Walker-syndrome and the Chiari-malformations are described by typical cases. In conclusion the reliability of diagnosis in all cases of midline-malformations will be mostly sufficient by plain axial computed tomograms due to very clearly defined unmistakable pictures.

In human genetics and orthopedics quite different answers have been given to the question of hereditary transmission and frequency of hip dysplasia in families of children with congenital hip dislocation. We therefore have made roentgenometric measurements of 110 parents of children with congenital hip dislocation. In 25% we found abnormal flat acetabulae, whereas 12% had pathologic deep hips. This may propose a new concept of morphology of congenital hip dysplasia.
