Unexpected death due to infectious mononucleosis
1Forensic Science Centre, Adelaide, Australia. byardr01@forensic.sa.gov.au
Abstract:
A 14-year-old boy with infectious mononucleosis died unexpectedly in hospital. The most significant finding at autopsy was the presence of marked bilateral tonsillar enlargement with considerable narrowing of the upper airway. There were no other underlying organic diseases that could have caused or contributed to death. Narcotic analgesia had been administered less than 2 h before death and may have contributed to respiratory compromise. The blood morphine level was 0.08 mg/L. Toxicological evaluation of individuals with obstructive lesions of the upper airway may, therefore, be a useful adjunct to the autopsy assessment of such cases as it may reveal factors exacerbating mechanical blockage.
Insights
A teenage boy with infectious mononucleosis experienced sudden death due to severe tonsillar enlargement obstructing his airway. Narcotic analgesia may have worsened his respiratory compromise, highlighting the need for toxicology in similar autopsy cases.
Area of Science:
- Forensic Pathology
- Pediatric Medicine
- Toxicology
Background:
- Infectious mononucleosis can lead to severe complications.
- Upper airway obstruction is a critical medical emergency.
Observation:
- A 14-year-old male with infectious mononucleosis died unexpectedly.
- Autopsy revealed significant bilateral tonsillar enlargement causing upper airway narrowing.
Findings:
- No other underlying organic diseases were identified as the cause of death.
- Narcotic analgesia administered shortly before death may have contributed to respiratory compromise.
- Blood morphine levels were measured at 0.08 mg/L.
Implications:
- Toxicological evaluation is crucial in autopsies of patients with upper airway obstruction.
- Identifying exacerbating factors like medication can refine post-mortem assessments.
- This case underscores the potential for airway compromise in infectious mononucleosis, especially with concurrent analgesic use.
