title: Meningeal extramedullary haematopoiesis mimicking subdural hematoma.
abstract: Extramedullary haematopoiesis is a compensatory phenomenon in diseases where erythrocyte production is diminished or destruction is accelerated. The authors describe a rare case of meningeal extramedullary haematopoiesis mimicking subdural hematoma. CT scan revealed a hyperdense subdural lesion at the right frontal region following head injury. The patient was operated on and the pathological examination of the subdural lesion showed extramedullary haematopoiesis.
