Unsuspected chronic subdural haematoma following a motor vehicle accident. A case report

A case of unsuspected chronic subdural haematoma following a motor vehicle accident is presented. Attention is drawn to some of the cardinal features of the lesion, viz. its insidious, often unrecognized evolution, its predilection for the elderly and the debilitated, and the difficulty attendant upon precise histological dating of longstanding lesions beyond approximately 6 months' duration. The pathogenesis of the lesion is reviewed.
