Pitfalls and Artifacts in the Neck at Autopsy

Area of Science:

• Forensic Pathology
• Toxicology
• Legal Medicine

Background:

• Diagnosing strangulation at autopsy presents significant challenges for forensic pathologists.
• Distinguishing ante-mortem injuries from postmortem artifacts is critical for determining cause of death.
• Accurate diagnosis impacts criminal justice proceedings, potentially leading to murder convictions.

Purpose of the Study:

• To review common pitfalls and artifacts encountered during postmortem examination of the neck.
• To enhance the pathologist's ability to interpret neck findings in strangulation cases.
• To provide an evidence-based approach for diagnosing strangulation.

Main Methods:

• Literature review of five key areas of difficulty in neck autopsy.
• Analysis of anatomical variations and postmortem changes.
• Discussion of interpretative challenges in forensic neck examination.

Main Results:

• Identified five primary areas of diagnostic difficulty: hyoid bone anatomy, triticeous cartilages, Prinsloo-Gordon hemorrhage, postmortem hypostatic hemorrhage, and resuscitation-related neck injury.
• These factors commonly lead to misinterpretation of neck trauma.
• Awareness of these specific pitfalls is essential for accurate diagnosis.

Conclusions:

• Accurate interpretation of neck findings at autopsy requires a thorough understanding of anatomical variations and postmortem artifacts.
• Addressing these five key challenges improves the reliability of expert opinions in strangulation cases.
• This knowledge is vital for the forensic pathologist to provide evidence-based conclusions in legal contexts.
