(A) Computed tomography showed a cervical varix following presentation with high fever. Computed tomography revealed an intrauterine pregnancy with no other cervical abnormality. (B) The bleeding focus and cervical varix with erosion. A dark-red color change was observed in the anterior cervical lip. (C) Transvaginal ultrasonography showed cervical hypervascularity. (D) Magnetic resonance imaging showed diffuse cervical prominence with a dilated vascular channel partially filled with thrombus. (E) Computed tomography angiography showed arterial and venous hypervascularity in the cervix, which was supplied with blood from the internal iliac artery.

Computed tomography revealed no focus for a fever, but a 4.5-cm cystic lesion was detected in the intrauterine cavity, suggesting early intrauterine pregnancy (Fig. 1A). Transvaginal color Doppler ultrasonography showed a dilated venous plexus with abundant blood flow in the uterine cervix, suggesting a cervical varix (Fig. 1B and C). MRI revealed a diffusely dilated vascular channel with thrombus filling the surrounding uterine cervix (Fig. 1D). CTA predicts a high likelihood of massive cervical bleeding caused by a missed abortion, uterine artery embolization can be considered before treatment. CTA revealed arterial and venous cervical hypervascularity with blood supplied by the internal iliac artery (Fig. 1E).
Appearance at the first visit after discharge. (A) Ultrasonography showed that the cervical varix had disappeared. (B) Colposcopy showed normal morphology.

Cervical varix was not detected on ultrasonography, but the cervical length was short (Fig. 2A). On colposcopy, the cervix had near-normal morphology, but a small red spot was observed, and the cervix seemed to be weakened, as noted for the cervix after conization (Fig. 2B).
