Summary
The radiodiagnostic signs of congenital basal encephalocele are well known. The case history described here shows that a long existing, acquired, traumatic transethmoidal encephalocele can cause the same roentgen appearance. The differences between the congenital and recent posttraumatic forms are indicated.
