Pneumoperitoneum on X-ray and CT: When a Small Free-Air Finding Becomes a Major Clinical Risk
Edited by ScholarGen MediAI Team Acute Abdominal Pain, Free Intraperitoneal Air, Small-Bowel Dilatation, and the Role of AI in Preventing Diagnostic Delay A man in his early 50s developed acute abdominal pain and abdominal distension beginning the previous evening. The initial abdominal imaging revealed something that can appear deceptively simple: free intraperitoneal air beneath the diaphragm. But this was not simply an abnormal black crescent on an X-ray.
