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.
胃壁黏膜脱垂是胃组织的死后自溶，最终可导致胃穿孔。这种病实体现在病理学家那里很常见，但在诊断放射科医生那里很少见到。我们报告了一例突然不明原因婴儿死亡（SUID）病例，该男孩在死后放射照片上发现有气腹，随后尸检证实是由于胃壁黏膜脱垂导致的死后胃穿孔引起的。放射科医生识别这种病实体很重要，以免将其误诊为肠穿孔，肠穿孔由生前的病理学引起，包括创伤。
