| Abstract |
|
Arachnoid cysts are benign cysts occuring in the cerebrospinal axis in relation to the arachnoid
membrane.
From Jan, 1974 unitl June, 1986. we evaluated the clinical features and outcome of the arachnoid
cyst by the review of the medical records and followup study of 20 cases in pediatric age group, and
the results are as follows:
1) The age distribution of the patients was from 2 months afte birth to 15 years of age, and the
mean age was 4.1+4.5 (mean+S.D.) years.
2) 50% (10 cases) of the patients had occurred the first symptom before 1 year of age.
3) Male was more frequently involved than female by the ratio of 3:1.
4) Epileptic seizure was the most common subjective neurologic symptom at the time of visiting
hospital (45%), and headache was the symptom of second incidence (40%), Another presenting
symptoms were vomiting (20%), developmental delay (15%), hemiparesis (10%), macrocephaly (10%),
and learning disability (5%).
5) The sites of the arachnoid cysts were temporal area by 85% and posterior fossa by 15%, and the
location of the right to left differences had no statistical significance.
6) Electroencephalography (EEG) was done to 9 patients, which of 7 cases experienced epileptic
seizure, but 2 cases did not have seizure activity. And all cases showed abnormal EEG waves.
7) The total outcome of the patients were followed-up and the rate of much improved patietns was
45% (9 cases). 9 patients had got medical treatment only (group A), and 11 cases were operated
surgically after medical treatment (group B). In group A, the rate of much improved patients was 55.
6% and in group B, it was 36.4%. However, we could not agree that the outcome of group A was
superior to that of surgically treated group, because the patients of group A were operated surgically
after the failure of medical treatment.
8) Three methods of operation (1) single burr hole drainage, (2) cystoperitioneal shunt operation,
(3) removal of the cyst after craniotomy were used. And there were no statisically significant
differences for the outcome among the three methods of operation. |
