The most common cause is a perforated abdominal organ, generally from a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. A perforated appendix seldom causes a pneumoperitoneum. Spontaneous pneumoperitoneum is a rare case that is not caused by an abdominal organ rupture.
In severe cases with perforation, an adjacent phlegmon or abscess can be seen. Dense fluid layering in the pelvis can also result, related to either pus or enteric spillage . When patients are thin or younger, the relative absence of fat can make the appendix and surrounding fat stranding difficult to see.
Common causes of an acute abdomen include a gastrointestinal perforation, peptic ulcer disease, mesenteric ischemia, acute cholecystitis, appendicitis, diverticulitis, pancreatitis, and an abdominal hemorrhage. However, this is a non-exhaustative list and other less common causes may also lead to an acute abdomen. [3]
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
Causes include perforation of the intestinal tract, pancreatitis, pelvic inflammatory disease, stomach ulcer, cirrhosis, a ruptured appendix or even a perforated gallbladder. [3] Risk factors include ascites (the abnormal build-up of fluid in the abdomen) and peritoneal dialysis. [4]

Common causes of pain in the abdomen include gastroenteritis and irritable bowel syndrome. [3] About 15% of people have a more serious underlying condition such as appendicitis, leaking or ruptured abdominal aortic aneurysm, diverticulitis, or ectopic pregnancy. [2] In a third of cases, the exact cause is unclear. [2]
It is a descriptive term which may be used for inflammation related to a bacterial infection or non-infectious causes (e.g. pancreatitis). Most commonly, it is used in contradistinction to a "walled-off" pus-filled collection , although a phlegmon may progress to an abscess if untreated. A phlegmon can localize anywhere in the body. [1]
