Pelvic inflammatory disease rarely complicates pregnancy. Although few in number, most of the previously reported cases have resulted in spontaneous abortion or intrauterine fetal demise. At 5 weeks gestation, a 20 year old gravida 2 para 1 underwent uterine curettage and diagnostic laparoscopy for a suspected ectopic gestation. Seventeen days later, she presented with severe bilateral lower abdominal pain, cervical motion tenderness, uterine tenderness, and bilateral adnexal tenderness. After 84 hours of intravenous cefazolin, gentamycin, and clindamycin, the patient had resolution of all symptoms. She then completed 14 days of outpatient antibiotic therapy with oral cephalexin. At 39 weeks gestation, she delivered a 3611 g male fetus via spontaneous vaginal delivery. Successful pregnancy outcome can occur after first trimester pelvic inflammatory disease.
