Abstract

Total 28 cases of intracranial cysts ofh high risk neonates were taken neurosonographic follow up study among210 cases which has been done since April, 1986 through August, 1987. The results were as follows: 1. Intracranialcysts occured in 28 cases among 210 high risk neonates taken on neurosonography. 2. Three were no differencesdepending on sex of patients or the maturity of neonates. 3. 8 cases among 28 cases had intracraninal cysts whichwere developed at previous hemorrhge sites and most cysts(6/8 cases) were developed on higher grade ICH, withwhich the higher grade of hemorrhage, the much more enlarged and the more prolognation in cyst absorption. 4, 20cases had developed cysts with no evidence of hemorrhage on initial neurosonography who had respiratoryproblem(4), sepsis(3), meningitis(1) and perinatal asphxia(6) as other reports. 5. Subependymal area was the mostcommon location of cysts(25/28 cases). 6. In following up the serial neurosonograms, the degree of resorption andremaining sequalae were different depending on the causes of size and location of cyst. Most of the smaller cystsless than 5mm were resolved in between 60-90 days. 7. The cysts resulted from initial ICH developed usually 7 daysafter, with findings of central echolucency, which followed by a thinner cyst wall. The smaller cysts resultedfrom non henorrhagic origin and had the same progression in resolution. 8. In one case with perinatal asphxia, thepatient had similier ultrasonographic findings of brain edema initially which was followed by U/S manifestation ofmixed echogenicity in the brain parenchyme with obliteration of gyrus and sulici in 1 week. Thereafter which wasturned to multiple septated cystic leukoencephalomalacia in the 3 weeks follow up study.
