INTRODUCTION
Pneumoperitoneum is a very common radiologic sign in patients with perforated peptic ulcer1,4,5. Much less likely, other gastrointestinal diseases may present1,2,3,4,5. The anatomo-radiologic correlation between them is a rare clinical event and frequently may lead to a diagnostic misinterpretation.
CASE REPORT
A 56-year-old man, presented to medical assistance with abdominal pain and distension associated with fever, vomit, absence of flatus and evacuation for about 14 days. He also reported treatment with herbal teas in the beginning, but without any success. The physical examination revealed a painful facial expression, anemia and severe dehydration. The abdomen was distended, tympanic, and diffusely painful on palpation mainly on right iliac fossae with Joubert's and Blumberg's signs. Leukocytosis (13.410/mm3), hypernatremia and hyperazotemia were present. Chest X-ray showed a pneumoperitoneum (Figure 1). The abdomen's radiography revealed a distension of the intestinal loop with hydroaereal signs and pneumoperitoneum. The patient went to surgerywith an exploratory laparotomy revealing diffuse peritonitis due to perforated appendicitis. Appendectomy, peritoneal cavity cleaning and drainage with tubular drains were carried out. After surgery, in intensive care unit, received Ertapenem 1g daily but severe sepsis lead him to death on the 16th post-operative day with multiple systemic failure.
DISCUSSION
Peritonitis caused by appendicitis is not usually related to pneumoperitoneum. It is a very rare situation reported on the medical literature with at most 7% estimated incidence 2,4. Few authors published anatomo-radiologic correlation between perforated appendicitis and pneumoperitoneum, but it can be more common than usually related in literature due to the lack of X-ray evaluation in established acute appendicitis1,2.
Two theories may explain the pathophysiologic mechanism for this correlation: 1) intestinal gas escapes from the perforated appendix and, 2) the increase in the gas production by the peri-appendicular abscess' bacteria2,4. In the present case, the first theory is probably the most appropriate to explain.
Körner et al.3 reported that patients with perforated appendicitis have an increase in the duration of the clinical symptoms and signs than patients with non-perforated appendicitis. This observation had been observed in our case.
CONCLUSION
Although rare as pneumoperitoneum ethiology, acute appendicitis may be thought as it's cause.
