Liver and Bilateral Tubo-Ovarian Abscesses Caused by Streptococcus constellatus in an Immunocompetent Adolescent: A Case Report.

Opportunistic infections most often occur in immunocompromised patients, however, they can also occur in immunocompetent patients. While rare, bacterial infections such as those from Streptococcus constellatus (S. constellatus) can cause severe pyogenic infections and abscess formations. It is important to understand the risk factors, diagnostic workup, and management of patients with this rare but enduring bacterial infection. Although most of the literature reports the prevalence of S. constellatus in adults, occurrences should not be overlooked in the pediatric population. We present a case of an immunocompetent 19-year-old female who initially presented with refractory fevers and was found to have an intrahepatic abscess and bilateral tubo-ovarian abscesses. Management of this patient included percutaneous drainage of the hepatic abscess and antibiotic treatment for 28 days.
