Respiratory syncytial virus (RSV) predominantly affects children and typically manifests as an upper respiratory tract infection. Primary RSV infection in immunosuppressed adults may increase risks of disseminated infection manifesting as RSV hepatitis. A 29-year-old pregnant woman of 10 weeks gestation presented with mild right upper quadrant abdominal pain, intractable nausea, and vomiting, requiring hospitalization. Due to initial lab work showing significantly elevated liver transaminases, she underwent a thorough workup to evaluate for causes of hepatitis. Common viral and autoimmune etiologies of hepatitis were excluded with appropriate serologies. A respiratory viral molecular panel (RVP) was obtained to evaluate for SARS-CoV-2/coronavirus disease 2019 (COVID-19) infection, despite lack of typical respiratory symptoms. No structural pathologies were detected on abdominal imaging with ultrasound and magnetic resonance imaging. No other etiologies for the patient's hepatitis were detected other than RSV infection detected on RVP. The patient's care required close coordination between multiple different subspecialties. Her condition improved due to the early detection of RSV infection and prompt initiation of supportive care. This case highlights the need for providers to consider obtaining an RVP early in workup of hepatitis to evaluate for RSV infection, even when patients have minimal respiratory symptoms. A high index of suspicion is required for early identification of RSV hepatitis as timely supportive care may prevent progression to acute liver failure.
