A rare case of community acquired serratia lung abscess in a patient with cardiac bronchus.

The incidence of lung abscess caused by Serratia marcescens is extremely low and is only reported in the immunocompromised population. We present a previously healthy woman with Serratia lung abscess in close proximity with an accessory cardiac bronchus. The patient was treated with appropriate antibiotics which led to complete resolution of the lesion. Our case highlights that individuals without medical co-morbidities may develop atypical lung infections like Serratia when associated with anatomic anomalies.
