Abstract: Loculated hydrocephalus (LH) is caused, most frequently, by
meningitis or intraventricular hemorrhage. However, uniloculated hydrocephalus
caused by neonatal intraventricular hemorrhage is uncommon. We report the case
of an infant who developed LH associated with antenatal intraventricular
hemorrhage during the neonatal period. LH was suspected by routine
ultrasonographic examination at 38 weeks' of gestation. A computerized
tomography scan on the 2nd day, after the child was born, confirmed dilatation
of the right lateral ventricle. Furthermore, magnetic resonance imaging
examination on the 6th day suggested subependymal hemorrhage in right lateral
ventricle. At 5 months' of age, the infant underwent endoscopic septum
pellucidum perforation for an increase in ventriculomegaly and also the size of
the head circumference. However, 2 months after surgery, a
ventriculo-peritoneal shunt was placed because of reappearance of
ventriculomegaly. Examination of the child, when she was 2 years old, showed
improvement of ventriculomegaly and the child was making appropriate
developmental progress.
