Image of the Week: Do you recognize the clinical triad in this emergency case?

A 35-year-old woman presents to the emergency department with lower abdominal pain and vaginal spotting. Her last menstrual period was nine weeks ago. She was treated for a chlamydial cervical infection in the past and has never taken oral contraceptives. On abdominal examination, no mass is detected, however, there is moderate tenderness in the right adnexal region. Laboratory studies reveal mildly low hemoglobin and elevated beta-human chorionic gonadotropin (hCG) levels. An ultrasound demonstrates the findings seen here. What other finding would be consistent with this patient’s most likely diagnosis? Learn more about this case, take the quiz, and join the conversation on Figure 1.
