title: Clinical correlates of erythropoiesis in chronic subdural hematoma.
abstract: Histologic investigation was performed in 38 out of 224 chronic subdural hematomas treated at our institution from 1978 to 1988. Nucleated red blood cells were found in 33% of the chronic subdural membranes examined. Additional sections were examined in 14 of these 38 patients, revealing erythroblasts in 57%. The clinical course and radiographic findings in the patients whose membranes contained erythroblasts were compared with those whose specimens did not. Neither history, presentation, size of hematoma, nor postoperative recovery differed from one group to the other. By comparing histologic and clinical findings, we are able to conclude that the production of erythrocytes by chronic subdural membranes is of no surgical significance.
