Subdural hematoma in patients with systemic cancer

We reviewed the medical records of 70 patients with systemic cancer in whom a subdural hematoma (SDH) developed. Among patients with a solid tumor, trauma and use of anticoagulants were common causes of SDH, and these patients had a relatively favourable outcome. Among patients with a hematologic cancer and in the rest of the patients with a solid tumor, coagulopathies and dural metastatic involvement were the most common causes of SDH. Recurrent SDH and death due to SDH were common in the latter group.
