Figure 1 Cervical histopathological results. A: Pathologic examination after loop electrosurgical excision procedure indicated cervical intraepithelial neoplasia grade 1; B: Pathologic examination of colposcopic cervical biopsy specimen revealed chronic inflammation of the cervical mucosa; C: Histopathologic evaluation confirmed adenocarcinoma in situ of the uterine cervix.

Figure 2 Uterine ultrasonography showed normal results. A and B: Ultrasonography showed that the uterus measured 5.3 cm × 4.0 cm × 4.1 cm, blood supply was normal, and the endometrium was 0.5 cm thick (A) and depicted a cervix with uniform blood supply and without any space-occupying lesion.

Figure 3 Pelvic magnetic resonance imaging revealed a normal uterus and cervix. A and B: Sagittal (A) and axial (B) pelvic magnetic resonance imaging showed normal uterine size and shape, no abnormal signals, and no obvious abnormal signal shadows in the bilateral adnexa.

Figure 4 Hysteroscopic view. A and B: Hysteroscopic examination revealed no significant hyperplastic changes in the endometrium (A) but showed inflammation of the cervical canal (B).
