A case of clinically undiagnosed chronic leukaemia: unexpected sudden death of a patient with whiplash injury.

This is the autopsy case of a 42-year-old male with whiplash injury who died sudderily and unexpectedly. The pathological diagnosis was chronic myelocytic leukaemia with involvement of the heart, spleen, lymph nodes, liver, kidneys and bone marrow. The immediate cause of death is considered to be heart failure resulting from leukaemic cell infiltration. In this case, the underlying leukaemia was masked by the persisting symptoms following whiplash injury, and left undiagnosed clinically.
