A 28-year-old woman, gravida 1 para 0, with twin gestation presents for routine anatomic survey at 20 weeks of gestation without any complaints. On transabdominal ultrasonography, the ultrasonographer notes concern for cervical funneling and proceeds to perform a transvaginal ultrasonogram, which reveals a short cervix of 18 mm.
Limited interventions are available for management of twin gestations in women with a short cervix for prevention of spontaneous preterm birth.

The Clinical Conundrums feature is an invited article type developed for clinicians who sometimes are faced with either clinical situations or patient questions for which little (if any) information is available to guide decision-making. Clinicians have all been faced with a situation in which they approach a trusted colleague and ask, “Can I run something by you?” The Clinical Conundrums feature attempts to provide answers to those types of questions.
