A Difficult Case to Swallow: Herpes Esophagitis After Epidural Steroid Injection

Herpes esophagitis due to infection with herpes simplex virus typically occurs in immunocompromised patients such as those with human immunodeficiency virus, malignancy, and those undergoing immunosuppressive therapy. Albeit rare, herpes esophagitis can occur in immunocompetent patients as a primary infection. We present a case of herpes esophagitis after corticosteroid treatment for back pain including epidural steroid injections. Corticosteroids, especially local injections, are a common treatment for chronic back pain, but they are not without risk. Epidural steroid injections can have systemic effects, which may go unrecognized and underappreciated. Although local infections have been reported after administering these injections, systemic immune suppression may allow for unexpected infections such as herpes esophagitis. Given the widespread use of epidural steroid injections, physicians should reevaluate the potential for harm when considering this treatment.
