Another Positive Pregnancy Test

A 16-year-old female presented to an emergency department with complaints of nausea and vomiting, dehydration, increasing weakness, and resting tremor. The past history included mild exercise-induced asthma. She denied sexual activity, but a urine test for beta-human chorionic gonadotropin was positive and she was transferred to a gynecology service for management of pregnancy. She also had primary amenorrhea and delayed growth for age. Further complaints included headaches accompanied with worsening of visual activity. Pelvic ultrasound revealed no intrauterine or ectopic pregnancy. Head CT scan showed a suprasellar tumor, better defined on an MRI as a hypothalamic tumor. Pathology following partial tumor resection revealed a mixed germ cell tumor with negative metastatic work-up.
