Tubo-Ovarian Abscesses in Nonsexually Active Adolescent Females: A Large Case Series.
The aim of the study was to review the incidence, presentation, and management of tubo-ovarian abscesses (TOA) in nonsexually active (NSA) adolescents. A retrospective chart review was performed at a single children's hospital. We evaluated self-reported NSA females aged < 21 years diagnosed with TOA. Demographics, presenting symptoms, medical history, laboratory studies, imaging, and treatment were reviewed. Sixteen NSA females met inclusion criteria, with one patient presenting with two separate TOAs. Mean age at diagnosis was 14.6 ± 1.8 years; all were menarchal. Presenting symptoms included abdominal pain (88%), fever (76%), and vomiting (53%). Eleven patients (65%) received transabdominal pelvic ultrasound, 2 (12%) had magnetic resonance imaging of pelvis, and 11 (65%) had computed tomography of abdomen/pelvis. All patients had negative gonorrhea and chlamydia testing. Thirteen (76%) had comorbid disease including obstructed hemivagina ipsilateral renal agenesis, active or recent appendicitis, or genitourinary tract anomalies. Sixteen cases underwent drainage via interventional radiology or surgery. Twelve cases (71%) had TOA fluid cultured; five (29%) grew Escherichia coli species. All cases received intravenous antibiotics, and 88% of cases continued outpatient oral antibiotics. Although uncommon in NSA females, patients with underlying comorbidities may be at increased risk for TOA formation. Providers should consider the diagnosis of TOA even in NSA females.
