"Appendicitis located in the RUQ often presents atypically compared to classical appendicitis. Cases of subhepatic appendicitis can present with pain in the RUQ and epigastric region in sharp contrast to the RLQ pain typically seen in a more commonly placed appendicitis 2. The unusual presentation can mimic pathology of gastric or hepatobiliary origin."

"During normal development of the gastrointestinal tract, the primitive gut undergoes rotation resulting in the appendix entering the subhepatic region before descending as the colon elongates 2. The appendix completely enters the RLQ roughly by 4 months of age 3. Malrotation of the gut results in the appendix remaining in a subhepatic position thus leading to an appendicitis located in the upper abdomen should it become inflamed."
"Subhepatic appendicitis refers to inflammation of the appendix in which the appendix and caecum have failed to descend inferiorly during normal development; resulting in a "subhepatic" position."
