Case Discussion

Mesenteric adenitis is a self-limiting inflammatory process that affects the mesenteric lymph nodes in the right lower quadrant and is clinically often mistaken for acute appendicitis.

Mesenteric adenitis is most common in children and adolescents although it may occasionally affect adults. 

In most cases, mesenteric adenitis is self-limiting and typically abates over the course of a few weeks.
