Diffuse abdominal pain and leukocytosis

Patient Data

Age: 35 years

The patient underwent open surgery after X-ray findings and acute appendicitis was found.

Case Discussion

The appendicolith, also known as “fecolith” or “corpolith”, represents calcified deposits in the appendix, and contributes to the pathogenesis of acute appendicitis. It is defined as an area of high attenuation measuring ≤ 1 cm that is located in the pericecal areas, or in cases of perforation in the Morrison's (Douglas) pouch.

The finding of an appendicolith may be sufficient evidence to perform a prophylactic appendectomy in asymptomatic patients, given the higher rate of perforation at the time of acute appendicitis.
