title: Benign adrenal cyst presenting in a pregnant patient.
abstract: Cystic lesions of the adrenal gland are uncommon, most often diagnosed incidentally during diagnostic imaging or autopsy. An adrenal cyst presenting as a pelvic mass in pregnancy offers the clinician a diagnostic and therapeutic dilemma. A 28-year-old black female presented for routine obstetric care at 26 weeks' gestation and was found on examination to have a 40-cm pelvic-abdominal mass. Ultrasound confirmation revealed the mass to be cystic and arising from the right pelvis. Laboratory tests including hematocrit, white blood cell count, electrolytes, rapid plasma reagin (RPR), and CA-125 were within normal limits. The patient underwent exploratory laparotomy and a 40 x 20 cm right adrenal cyst was identified and resected. Postoperatively, the patient developed preterm labor and delivered a 955-g infant; the infant was discharged home 3 months later with bronchopulmonary dysplasia and delayed developmental milestones. The woman was discharged home without complication on postoperative Day 8. Accurate preoperative determination of the origin of a pelvic mass occurring in pregnancy is helpful in timing therapeutic intervention. Use of ultrasound and magnetic resonance imaging (MRI) modalities can provide detailed anatomical information without risk to mother or fetus. Conservative management of adrenal cyst in pregnancy may lower the morbidity and mortality of the mother and fetus.
