Abstract:
Gastromalacia is a postmortem autolysis of gastric tissue that can culminate in gastric perforation. This entity is well-recognized by pathologists but is rarely encountered by diagnostic radiologists. We are reporting a case of sudden unexplained infant death (SUID) in which a boy was found to have pneumoperitoneum on postmortem radiographs, subsequently proved by autopsy to be caused by postmortem gastric perforation resulting from gastromalacia. It is important for radiologists to recognize this entity so as not to mistake it for bowel perforation caused by antemortem pathology, including inflicted trauma.
Insights
Gastromalacia, a postmortem gastric tissue autolysis, can cause perforation. Radiologists must distinguish this from antemortem bowel perforation to avoid misdiagnosis in infant deaths.
Area of Science:
- Forensic Pathology
- Radiology
- Pediatric Autopsy
Background:
- Gastromalacia is postmortem autolysis of gastric tissue leading to perforation.
- It is a known entity among pathologists but infrequently recognized by radiologists.
- Distinguishing postmortem from antemortem findings is crucial in forensic cases.
Observation:
- A case of sudden unexplained infant death (SUID) is presented.
- Postmortem radiographs revealed pneumoperitoneum.
- Autopsy confirmed postmortem gastric perforation due to gastromalacia.
Findings:
- Gastromalacia resulted in gastric perforation and pneumoperitoneum.
- The findings were identified on postmortem radiographs.
- Autopsy confirmed the cause of death and the gastric perforation.
Implications:
- Radiologists must be aware of gastromalacia to prevent misinterpretation of postmortem findings.
- Misdiagnosis could lead to incorrect conclusions regarding the cause of death, particularly in cases of suspected trauma.
- Accurate identification aids in determining the timeline of events in infant deaths.
