An Interesting Case of Appendicolith Mimicking GB Calculus – A Case Report

An appendicolith is defined as a calcified mass within the lumen of the appendix formed by the aggregation of fecal particles and inorganic salts.[1] Appendicolith can present with varied clinical features. With the advent of MDCT, the incidental identification of appendicolith in asymptomatic patients has increased in its prevalence. However, in a case series by Ranieri D et al., an appendicolith obstructing the lumen of the appendix, causing appendicitis was found in the CT scans of 38.7% of patients presenting with acute abdomen as suspected appendicitis.[2] Appendicitis, which is caused by appendicolith, is more commonly associated with perforation and abscess formation.[3] Appendicolith with appendicitis usually presents with intermittent right lower quadrant pain, rebound tenderness and fever.[4] But an appendicolith presenting as right upper quadrant pain mimicking a gallstone disease is a rare presentation.
