Fulminant septicemic syndrome of Bacillus cereus in a leukemic patient.

We report a rapidly fatal Bacillus cereus septicemia in a leukemic patient receiving remission-induction therapy. Symptoms resembling food poisoning and fever preceded coma accompanied by neurologic abnormalities. Autopsy revealed necrotizing leptomeningitis with subarachnoid hemorrhage and coagulation necrosis of the liver with bacterial infiltration. These clinicopathologic findings were closely similar to those of reported cases. Because of a rapidly fatal clinical course, suspicion of this syndrome early in the course is important to determine an appropriate treatment. Therefore, we propose that this type of septicemia should be termed as fulminant septicemic syndrome of Bacillus cereus.
