title: Cervical varix complicated by placenta previa: A case report and literature review.
abstract: Uterine cervical varix is rare, and its clinical course is poorly understood. Therefore, we present a case report of cervical varix complicating placenta previa before describing our findings in the context of an electronic database search of relevant reports. In the case report, we describe the clinical course and imaging results of a 35-year-old woman who was diagnosed with cervical varix complicated by placenta previa. Investigation by magnetic resonance imaging, serial ultrasonography, and speculum confirmed the diagnosis, and a healthy baby was successfully delivered at 36 weeks of gestation by cesarean section. An electronic search identified nine previous cases of cervical varix complicated by placenta previa in the literature. Clinicians should be aware of cervical varices when managing placenta previa to avoid iatrogenic rupture or misdiagnosis of placenta accreta by magnetic resonance imaging.
