Abstract
Optic glioma associated with bilateral subduraleffusion in a four-month-old male infant was reported.
Clinical analysis of the cases with associationof subdural effusion or hematoma and braintumor in the world litereture was also performed.
When subdural effusion is found in newborn orolder infant, we should make sure whether or notan associated or masked brain tumor is presentsimultaneously. Care also should be taken tosearch for an underlying brain tumor and excludedural metastasis of extracranial malignant tumor, when we deal with chronic subdural hematoma in adult regardless of history of head injury.
