Radiology Resident Case of the Week: September 22, 1995
Acute Appendicitis
Marta Bogdanowicz
Peer Review Status: Internally Peer Reviewed
Etiology/Pathophysiology:
Impaction of an appendicolith, with consequential obstruction of the outflow of the appendix and inflammation of the wall. Obstruction of lumen by lymphoid hyperplasia (60%), fecolith(33%), foreign body (4%), stricture, tumor, parasite and Crohn's stricture are also causes of obstruction.
Pathology:
There was found to be evidence of acute appendicitis, focal regions of hyalinizing granuloma and no perforation.

Synonyms and related keywords: typhlitis, vermiform appendix, appendectomy, acute abdominal pain, appendiceal lumen, lymphoid hyperplasia, irritable bowel disease, IBD, fecal stasis, fecaliths, lymphoid hyperplasia of the appendix, obstruction of the appendiceal lumen, periappendicular abscess, peritonitis
Appendicitis occurs more frequently in males than in females, with a male-to-female ratio of 1.7:1.
Etiology: Appendicitis is caused by obstruction of the appendiceal lumen. The causes of the obstruction include lymphoid hyperplasia secondary to irritable bowel disease (IBD) or infections (more common during childhood and in young adults), fecal stasis and fecaliths (more common in elderly patients), parasites (especially in Eastern countries), or, more rarely, foreign bodies and neoplasms.

Common Misspelling: appendics
The cause of appendicitis is usually unknown. It may occur after a viral infection in the digestive tract or when the opening connecting the large intestine and appendix is blocked. The inflammation can cause infection, a blood clot, or rupture of the appendix. Because of the risk of rupture, appendicitis is considered an emergency. Anyone with symptoms needs to see a doctor immediately. Symptoms include
Lymphoid hyperplasia of the appendix may be related to Crohn disease, mononucleosis, amebiasis, measles, and GI and respiratory infections. Fecaliths are solid bodies within the appendix that form after precipitation of calcium salts and undigested fiber in a matrix of dehydrated fecal material.
Pathophysiology: Reportedly, appendicitis is caused by obstruction of the appendiceal lumen from a variety of causes. Independent of the etiology, obstruction is believed to cause an increase in pressure within the lumen. Such an increase is related to continuous secretion of fluids and mucus from the mucosa and the stagnation of this material. At the same time, intestinal bacteria within the appendix multiply, leading to the recruitment of white cells and the formation of pus and subsequent higher intraluminal pressure.
If appendiceal obstruction persists, intraluminal pressure rises ultimately above that of the appendiceal veins, leading to venous outflow obstruction. As a consequence, appendiceal wall ischemia begins, resulting in a loss of epithelial integrity and allowing bacterial invasion of the appendiceal wall.
Various specific bacteria, viruses, fungi, and parasites can be responsible agents of infection that affect the appendix, including Yersinia species, adenovirus, cytomegalovirus, actinomycosis, Mycobacteria species, Histoplasma species, Schistosoma species, pinworms, and Strongyloides stercoralis.
