Incidental Finding of a Persistent Right Vitelline Artery in a 13-Year-Old Boy with Acute Appendicitis: A Case Report with Clinico-Pathological Correlation and a Comprehensive Literature Review.

The persistence of fetal vitelline structures may occur. The primary intestinal arterial supply development happens normally in this scenario, but a vitelline vascular remnant (VVR) persists. A 13-year-old boy with a history of severe and intermittent abdominal pain since early infancy presented to the Emergency Department with clinical, analytical, and ultrasonographic findings suggestive of acute appendicitis.

Blastocystis hominis -associated Acute Appendicular Peritonitis in a 9-Year-old Boy: A Case Report and a Comprehensive Review of the Literature.

We report the case of a 9-year-old Spanish male who presented with peritonitis secondary to acute appendicitis with abundant intra-abdominal turbid-free fluid.
