Acute Appendicitis and Pneumatosis in a Duplicated Appendix With Schistosoma Remnants.
Appendiceal pneumatosis is rare, reported either in the context of acute appendicitis or enterocolitis. Here, we report the case of an elderly adult in whom the acute appendicitis was associated with pneumatosis and occurred in the context of a malformed appendix with pathogenic organism remnants. A 72-year-old man presented with abdominal pain 3 weeks after posttraumatic dorsolumbar surgery. The computed tomography scan showed acute appendicitis and 2 diverticula. On microscopy, the appendix showed acute appendicitis along with a Cave-Wallbridge type A duplication. In addition, several optically clear spaces were observed in the entire appendiceal wall consistent with pneumatosis of the appendix. Focally, calcified structures suggesting pathogenic organisms such as Schistosoma were noted as well. In conclusion, we report a case of appendiceal pneumatosis occurring in the context of acute appendicitis in a duplicated appendix, with presence of calcified structures suggestive of pathogenic organisms.
