Introduction: Unilateral pulmonary edema can mimic as pneumonia and is often misdiagnosed.
Case description: We describe a case of cardiogenic unilateral lobar pulmonary edema in a HIV infected and diabetic patient without known history of cardiac disease.
Conclusion: Rarely, unilateral pulmonary edema can present as a lobar consolidation and be confused with pneumonia. High index of suspicion and response to treatment of heart failure can clinch the diagnosis.
