Long-term follow-up of children and juveniles with arachnoid cysts.

In the vast literature on intracranial arachnoid cysts, communication of long-term follow-up is rare. Therefore, we studied the case histories of 60 children and juveniles operated on in our hospital since 1951. The most favorable cases were patients with temporal cysts: 93% recovered fully or with only slight deficits. In other locations (frontal, parietal, occipital, infratentorial), the percentages for a favorable course were lower. The reason cannot be attributed to the operation procedures. Independent of the surgical procedure, there were no postoperative deaths after 1969. Long-term follow-up revealed that, depending on the location of the arachnoid cyst, a high percentage (62%-93% of patients) had normal physical and social development with satisfactory quality of life.
