Figure 3. Appendicitis in a 33-year-old woman who was 17 weeks pregnant and had RLQ pain and fever. Axial T2-weighted single-shot fast SE image of the lower abdomen shows the cecum (C) and terminal ileum (TI). The appendix (arrow) is identified posterior to the cecum. The appendix is enlarged (8-mm diameter) and thick walled and its lumen is filled with high-signal-intensity fluid, whereas the cecum and terminal ileum are completely filled with negative oral contrast material. The MR imaging findings were consistent with early appendicitis, which was confirmed at surgery.
