[Differential roentgenodiagnosis of congenital craniocerebral hernias].

Ninety-three patients with congenital craniocerebral hernia were subjected to clinical and X-ray examination. Signs characteristic of each type of congenital craniocerebral hernias were detected. Congenital craniocerebral hernia was combined with other developmental anomalies of the skull and brain in 31% of cases. Differential X-ray diagnosis is made between congenital craniocerebral hernias and traumatic birth hernias, traumatic midline hernias, cholesteatoma, dermoids and epidermoids of the orbit, polyps, papilloma, and fibrous tumors. It was established that X-ray examination plays a very important role in disclosing the bone hernial canal. The surgeon must have an exact idea of this canal before undertaking operation for plastics of the hernial defect.
