Endometrial carcinoma with cervical stromal invasion: Three case reports

Figure 1 Endometrial carcinoma involving the cervical stroma in Case 1. A: On the T2WI image, the endometrium appears slightly thickened and extends downwards into the intra-cervical inlet area (arrow), showing a clear boundary with the cervix. The mucosa within this region exhibits a cyst; B: On the diffusion weighted imaging image, no obvious hyperintensity is evident in the endometrium, while the endocervical stroma appears hypointense (arrow); C: On the enhanced image, the endometrium does not exhibit uniform enhancement, with a distinct demarcation from the muscle layer (arrow).

Figure 2 Endometrial carcinoma involving the cervical stroma in Case 2. A: On the T2WI image, polypoid nodules were observed within the mucosa of the intrauterine cervical orifice region (arrow), showing a clear boundary with the cervix; B: On the DWI image, the nodule exhibited a slightly hyperintense signal (circle), while the endocervical stroma displayed a hypointense signal (arrow); C: On the enhanced image, the nodule was marginally enhanced and distinctly separate from the endocervical stroma (arrow).

Figure 3 Endometrial carcinoma involving the cervical stroma in Case 3. A: On the T2-weighted imaging image, the endometrium cannot be seen, with fluid accumulation in the cavity (circle). The cervix stroma is depicted as low signal (arrow); B: On the diffusion weighted imaging (DWI) image, the fluid accumulation within the cavity is blood, and the DWI displays a slightly elevated signal (circle). Additionally, the myometrium exhibits a marginally high signal (triangle), while the cervix interstitial region maintains a low signal (arrow); C: On the enhanced image, the endometrium cannot be seen, while the muscle layer shows marked prominent enhancement (triangle). The cervical stroma shows hypo-enhancement (narrow arrow), but the mucosa is significantly enhanced (bold arrow).
