Pelvic magnetic resonance imaging (MRI) showed a cervical tumor 40 mm * 36 mm * 48 mm in size, without invasion of the uterus and vagina, and no pelvic lymph node metastasis.

MRI of the pelvis showed that the cervical mass was about 40 mm * 36 mm * 48 mm, invading the lower part of the uterine body and pelvic vessels, but without parametrial, vaginal extension and enlarged pelvic lymph nodes ( Figure 1 ).
The cervix is widened with mass radioactive concentration foci, with a range of about 38 mm * 24 mm, SUVmax 4.0, delay 5.2. Radioactive concentration can be seen in the lower part of the uterine body, SUVmax 3.9, delay 5.6. Uterine effusion.

PET-CT showed that there were a large number of radioactive foci in the cervix and lower uterine segment, which were suspected to be malignant tumors, but there was no obvious radioactive foci, suggesting lymph node metastasis in the pelvic cavity and distant metastasis ( Figure 2 ).

The width of the parauterine tissues on both sides was measuredto be about 3 cm, the length of the vaginal resection was about 3 cm, and there was no significant increase in pelvic lymph nodes on both sides ( Figure 3 ).
Histological (A-D; hematoxylin and eosin staining) results. (A) Microscopic examination showed that atypical glands are irregular and expand with gastric differentiation. (B) The tumor showed gastric differentiation, including an atypical nucleus and abundant eosinophilic cytoplasm that was transparent or pale. (C) The tumor invaded the myometrium. (D) Tumor cells metastasized to local lymph nodes.

Two of the 20 pelvic lymph nodes showed metastasis and invasion ( Figure 4 ).
