cervical pregnancy is an uncommon ectopic pregnancy that accounts for less than 1% of such gestations. 1 This condition is associated with an extremely high risk of massive hemorrhage and previously often required hysterectomy. 1 The current diagnostic modality of this potentially lifethreatening condition is transvaginal sonography, supported at times by magnetic resonance imaging. [2][3][4] The definitive diagnostic imaging feature of a cervical pregnancy is the location of a gestational sac in the cervix in the presence of a closed internal uterine cervical os. [2][3][4][5][6][7] We report the 3-dimensional transvaginal sonographic findings of a cervical pregnancy at 6 weeks' gestation.Received August 8, 2007,
Case ReportA 34-year-old woman, gravida 3, para 0, came to the emergency department at State University of New York Downstate Medical Center with mild uterine hemorrhage. Her medical history was unremarkable. The patient had 2 previous spontaneous first-trimester miscarriages. Physical examination revealed a healthy individual. She was afebrile with a blood pressure of 120/78 mm Hg, a pulse of 84 beats per minute, and a respiratory rate of 20 breaths per minute. Her abdomen was soft and nontender, with no peritoneal signs elicited. Bimanual pelvic examination disclosed a soft, mildly enlarged uterus. Both adnexa were normal. The cervix was long and closed and appeared boggy on inspection.Laboratory test results revealed a hemoglobin level of 13.6 g/dL, a hematocrit value of 42%, a white blood cell count of 7.29 × 10 9 /L, and a platelet count of 255 × 10 9 /L.
