Ultrasonographic findings in the periventricular region in premature newborns with antenatal periventricular leukomalacia.
Cranial ultrasonography was carried out at least three times a week during the first 16 days of life in all 53 premature newborns born within study period. If a cyst of more than three mm was detected in the periventricular region by fourteenth day of life, it was judged to be antenatal PVL. Periventricular echodensity was classified into mild, moderate or severe periventricular echodensity (PVE). Among 53 newborns, 11 babies (20.8%) were diagnosed as having antenatal PVL. Cysts were observed in the first two days in 9 cases (81.8%) out of 11 babies, and in bilateral periventricular regions in 8 cases (72.7%) out of 11 babies. All 3 babies with severe PVE in the periventricular region had PVL at the time of diagnosis or developed PVL shortely after severe PVE was detected.
