Imaging of appendicitis: Computed tomography, magnetic resonance imaging, and ultrasound in diagnosis and management

Figure 1 On the left is a computed tomography image of normal healthy appendix while on the right is an inflamed appendix with fat stranding.

Figure 2 Image. A: Computed tomography showing appendiceal wall hyperenhancement. White arrow: Inflamed, enhancing appendiceal wall consistent with acute appendicitis; B: Computed tomography showing airless, low attenuation fluid in the lumen, a frequently useful sign in early appendicitis. White arrow: Fluid-filled, non-aerated lumen measuring 2.6 mm, indicating early mucosal inflammation; C: Distended appendix fluid filled, curvilinear calcifications at base with airless low attenuation fluid, which was identified as a mucocele (orange arrow).
