Fever and elevated white blood cell count – Indicate infection
Rebound tenderness – Common on physical examination
Generalized abdominal discomfort – Seen in chronic or atypical cases

Diagnosis

Diagnosis of Other appendicitis includes physical exam, abdominal ultrasound or CT scan, complete blood count, and occasionally laparoscopy. Imaging helps rule out perforation, abscess, or other abdominal pathologies.
