Growing skull fractures of childhood. Possible mechanism of its focal ventricular dilatation.
Four cases of growing skull fracture are presented. Pneumoencephalography done on these cases showed a moderate to extensive degree of focal ventricular dilatation beneath the skull defect. An important factor, heretofore overlooked in explaining this focal ventricular enlargement, is our hypothesis that the force exerted on the particular area of the ventricular wall represents a pulsatile CSF movement damped in the region which is liable to yield to this compression wave in the absence of covering resistant dura mater. Because of the importance of early diagnosis in order to avoid possible delayed neurologic complications such as convulsive disorders, it is advisable to carry on repeated radiological examinations of the skull following fracture in this particular age group until the fracture heals by the progressive apposition of the bone on either side of the fractured line.
