Unusual Appendicitis Presentations
Purpose or Case Report:
Timely sonographic diagnosis of appendicitis can be critical for pediatric patients, as perforation rate is inversely related to the child’s age, and atypical signs and symptoms can commonly obscure the clinical diagnosis.1 In experienced hands, pediatric sonography for appendicitis has a high sensitivity and specificity and spares the child radiation.2 Our educational poster entitled “Unusual Appendicitis Presentations” has been authored by experienced sonographers and will cover the following:
1. Scanning protocols and techniques used at our institution
2. Helpful tips that go beyond routine imaging to detect difficult appendicitis findings
3. Uncommon cases including neonatal, duplicated, mucinous, gangrenous, and disrupted appendicitis involving the bladder wall
4. Images from each case as well as patient symptoms, imaging findings and surgically confirmed diagnosis
