title: Congenital brain defect masked by subdural fluid collection.
abstract: Two rare cases of subdural fluid collection are reported. In these cases, the subdural space was in direct communication with the lateral ventricle through the congenital brain defects. The subdural fluid was formed by the cerebrospinal fluid which passed from the lateral ventricle through the brain defects. The difficulty to diagnose these cases from the usual subdural hygroma is emphasized.
