The Significance of Adrenal Hemorrhage: Undiagnosed Waterhouse‐Friderichsen Syndrome,A Case Series

A retrospective series of five cases of nontraumatic gross adrenal hemorrhage were identified in 800 consecutive forensic autopsies. All patients were males, of different ethnicities and with ages ranging from 2 to 48 years. All patients had a clinical history and autopsy findings suggestive of sepsis. Pre‐ or postmortem microbiological cultures were variably positive for Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus aureus, and methicillin‐resistant Staphylococcus aureus. The fifth case was positive for yeast and a coagulase negative staphylococcus; contamination of this culture medium cannot be excluded. No cases had a culture positive for Neisseria meningitidis. We find that the reviewed patients with grossly or microscopically identifiable adrenal hemorrhage were otherwise healthy individuals who died suddenly as a consequence of bacterial infection. In each case, signs and symptoms compatible with premortem adrenal insufficiency were reported; in no instance was the adrenal hemorrhage clinically identified.
