Decoding the Medical Language in Your Loved One’s Autopsy Report
Receiving your loved one’s autopsy report is an emotional moment, and the dense medical terminology can make it feel impenetrable. Autopsy reports are written by pathologists for other medical professionals, using standardized anatomical language and diagnostic terminology that most families have never encountered. This guide translates the major sections of a typical autopsy report into plain language, helping you understand what each part means and what the findings tell you about how your loved one died.
Structure of a Typical Autopsy Report
Most autopsy reports follow a standard format that includes several sections, each serving a specific purpose:
Header Information
The report begins with identifying information: the deceased’s name, age, sex, date of death, date of autopsy, case number, and the name of the performing pathologist. This section also typically lists the requesting authority (medical examiner, coroner, or private client).
Clinical Summary / History
This section summarizes what was known about the deceased and the circumstances of death before the autopsy began. It may include the deceased’s medical history, medications, circumstances of the death as reported by law enforcement or the family, and hospital records if the person died in a medical facility. The pathologist uses this information to guide the examination and interpret findings in context.
External Examination
The external examination documents everything the pathologist observes on the outside of the body before making any incisions. This includes the general description of the body, noting height, weight, body type, and overall condition. It records identifying features such as scars, tattoos, birthmarks, and dental condition. The clothing and personal effects are described. Any injuries visible on the body surface are documented, including their precise location, size, shape, and characteristics. Signs of medical treatment such as surgical incisions, IV sites, or defibrillator pad marks are noted.
Internal Examination
This is the most detailed section and describes the findings in each organ system. It is typically organized by body region or system:
Cardiovascular system: The heart’s weight, size, and condition. Coronary arteries are examined for blockages (atherosclerosis), described as percentages of narrowing. Heart valves are inspected for abnormalities. The heart muscle (myocardium) is examined for signs of old or recent damage.
Respiratory system: The lungs’ weight and condition. Findings such as pneumonia, fluid accumulation (edema), blood clots (pulmonary emboli), or tumors are described.
Central nervous system: The brain’s weight and appearance. Evidence of bleeding (hemorrhage), swelling (edema), tumors, or degeneration is documented.
Gastrointestinal system: The stomach contents (which can help establish time of death), condition of the liver, intestines, and other digestive organs.
Genitourinary system: The kidneys, bladder, and reproductive organs.
Musculoskeletal system: Bones and muscles, particularly important when trauma is involved.
Microscopic Examination (Histology)
This section describes what the pathologist found when examining tissue samples under the microscope. Microscopic examination can reveal things not visible to the naked eye, such as early-stage cancers, microscopic blood clots, inflammation patterns indicative of infection, changes in heart muscle tissue after a heart attack, and drug-related changes in organ tissue. This section uses highly technical language and is often the most difficult for families to understand.
Toxicology
The toxicology section lists all substances detected in the body and their concentrations. Results are typically reported in nanograms per milliliter (ng/mL) or milligrams per liter (mg/L). The report may include a reference range showing what concentrations are considered therapeutic (normal treatment level), toxic (dangerously high), or lethal. It is important to note that postmortem drug levels cannot be directly compared to levels in living people due to postmortem redistribution.
Cause and Manner of Death
This is often the section families turn to first. The cause of death is the disease, injury, or condition that directly caused the death. It is listed in a specific format: the immediate cause of death on the first line, with contributing conditions listed below in order of their causal relationship. For example, the immediate cause might be “pulmonary embolism,” with “deep vein thrombosis” listed as the underlying condition, and “immobilization following hip fracture” as the initiating event.
The manner of death is the pathologist’s determination of the circumstances: natural, accident, suicide, homicide, or undetermined.
Common Medical Terms Explained
Here are some frequently encountered terms in autopsy reports and their plain-language meanings:
- Atherosclerosis: Hardening and narrowing of arteries due to plaque buildup. Often described as a percentage of narrowing (e.g., “75% stenosis of the left anterior descending coronary artery” means that artery is three-quarters blocked)
- Edema: Swelling caused by fluid accumulation. Pulmonary edema (fluid in the lungs) and cerebral edema (brain swelling) are common findings
- Hemorrhage: Bleeding. May be described by location: subdural (under the brain’s covering), subarachnoid (around the brain), retroperitoneal (behind the abdominal organs)
- Cirrhosis: Scarring of the liver, often associated with chronic alcohol use or hepatitis
- Cardiomegaly: Enlarged heart, often associated with high blood pressure, heart valve disease, or cardiomyopathy
- Aspiration: Inhalation of foreign material (such as vomit) into the lungs, which can cause death by blocking airways or triggering pneumonia
- Contusion: A bruise — bleeding within tissue caused by blunt force
- Laceration: A tear in tissue, often caused by blunt force (as opposed to an incision, which is a clean cut)
- Petechiae: Tiny pinpoint hemorrhages, often seen in the eyes and face in cases of asphyxia (suffocation or strangulation)
- Autolysis: Self-digestion of tissues after death, a normal decomposition process that can affect the pathologist’s ability to interpret findings
Questions to Ask the Pathologist
After reading the report, you are entitled to ask the pathologist to explain any findings you do not understand. Helpful questions include: Can you explain the cause of death in everyday language? Were there any surprising or unexpected findings? Could the death have been prevented with different medical care? Are there any findings that suggest a hereditary condition that could affect our family? What do the toxicology results mean in practical terms? Are there any findings that remain uncertain or require further investigation?
Most pathologists are willing to schedule a phone call or meeting to discuss their findings with the family. If the report was issued by the medical examiner’s office, contact their family services coordinator to arrange this conversation.
