Dural metastases in chronic myeloid leukemia presenting as subdural hematoma.

Subdural hematoma (SDH) has been reported in 0.5-4% of all intracranial metastatic tumors. Chronic SDH has been reported in intracranial metastases from both solid and haematological malignancies. Here we report recurrent SDH in a patient with chronic myeloid leukaemia (CML) following dural metastases. An elderly male patient a known case of CML was admitted to our casualty with symptoms of headache and altered sensorium and imaging revealed a large right fronto temporo parietal chronic SDH. This was surgically managed and histopathology of the duramater and subdural membrane confirmed infiltration with leukemic cells. The pathogenesis of chronic SDH in malignancies is multifactorial and this case report throws light on leukemic infiltration of duramater as a cause for chronic SDH other than coagulopathy.
