Appendicitis
Pinto Leite et al proposed an Algorithm for Interpretation of Appendicitis CT in Symptomatic Patients1
- 1. Excludes appendicitis
- CT findings: < 6-mm appendix or > 6-mm appendix completely gas-filled.
Recommendation : Work up other causes of RLQ pain
- CT findings: < 6-mm appendix or > 6-mm appendix completely gas-filled.
- 2. Possible appendicitis
- CT findings: 6- to 10-mm appendix without any other CT
signs.
Recommendation : Observation if symptomatic
- CT findings: 6- to 10-mm appendix without any other CT
signs.
- 3. Probable appendicitis
- CT findings: 6- to 10-mm appendix +wall thickening + wall hyperenhancement (no fat stranding).
Recommendation : Surgery if symptomatic
- CT findings: 6- to 10-mm appendix +wall thickening + wall hyperenhancement (no fat stranding).
- 4. Definite appendicitis
- CT findings: > 10-mm appendix or 6- to 10-mm appendix +
wall thickening + wall hyperenhencement+ fat stranding.
Recommendation: Surgery if symptomatic
- CT findings: > 10-mm appendix or 6- to 10-mm appendix +
wall thickening + wall hyperenhencement+ fat stranding.
In our case example above the imaging findings are suggestive of "probable appendicitis". Patient subsequently underwent appendectomy without complication.
