Abstract:
Dandy-Walker cyst is a rare disease causing hydrocephalus as a result of congenital outlet obstruction of the fourth ventricle. The clinical and C-T findings in two cases of the Dandy-Walker cyst which were confirmed through posterior fossa exploration are described. The patients were an infant and a girl aged 8 months and 16 months, who had presented signs of increased intracranial pressure for relatively short periods before admission. Brain C-T scan showed a generalized hydrocephalus with a large CSF-filled cystic space in the posterior fossa, indicating a defect of cerebellar vermis. Arachnoid cyst, megacisterna magna, ependymal cyst, and porencephalic cyst should be included in differential diagnosis and brain C-T scan alone is not sufficient in pathologic differentiation Posterior fossa exploration and cystic membrane excision were done in both cases with simultaneous ventriculo-peritoneal shunt in the latter case.
