Intracranial dural metastasis presenting as chronic subdural hematoma: a case report and review of literature.

Intracranial dural metastasis presenting as chronic subdural hematoma is a relatively rare clinical scenario. There are different theories explaining the formation of subdural hematoma in such cases. In this report we present a case of chronic subdural hematoma in a 44-year old lady who did not have any clinical evidence of primary tumour anywhere in the body. This lady died in spite of two emergency surgeries. During second surgery, the subdural membrane was sent for histopathological examination which revealed presence of metastatic tumour. We discuss the case along with a review of literature and recommend subdural membrane biopsy in all cases of chronic subdural hematoma.
