Imaging features of appendiceal signet ring cell carcinoma with uterine implantation: A case report

Figure 1 Computed tomography features of the appendix and uterus. A: Computed tomography (CT) enhanced coronal view: Coarsening appendix (arrowhead), strengthening after enhancement, clear boundary between focus and surrounding tissues; B: CT enhanced sagittal view: Obvious uterus enlargement, obvious muscular.

Figure 2 Magnetic resonance imaging features of appendix and uterus. A: T2-weighted imaging (T2WI) transverse view: Coarsening appendix (arrowhead), T2WI high signal, and signals are relatively uniform; B: T2WI sagittal view, obvious thickening mesometrium (arrowhead), and ambiguous display of bonding zone; C: Diffusion-weighted imaging, the enlarged uterus presents slightly high signals; D: T1-weighted imaging enhanced sagittal view, strengthening mesometrium and relatively complete serosa.
