Case Discussion

Presented to the ER in the morning with right lower quadrant abdominal pain radiating to the groin that had started as diffuse abdominal pain the previous evening. Had vomited after having eaten a "bad" pizza, since then felt nauseous.
On physical examination: right lower abdominal tenderness with local peritoneal irritation.
Full blood count: 13K leukocytes with a mild left shift.

Ultrasonography showed signs of acute appendicitis and a left pelvic kidney was discovered.

Acute appendicitis was confirmed at surgery:
"Acute phlegmonous appendicitis, its tip covered in fibrin, adhering to the peritoneum."
