Unilateral lobar pulmonary edema.

Pulmonary edema is usually bilateral, but unilateral lobar pulmonary edema can also be encountered in clinical practice. We describe a case of unilateral lobar pulmonary edema in a patient without known cardiac history. It was first presentation of underlying cardiac disease in our patient and was difficult to differentiate from pneumonia. Unilateral pulmonary edema can mimic as pneumonia. Clinician should be aware of differential diagnosis of pulmonary edema, otherwise it can lead to unnecessary investigation and delay in starting definitive treatment.
