An 80-year-old man with a right upper lobe opacity

Area of Science:

• Cardiology
• Pulmonology
• Radiology

Background:

• The differential diagnosis for a right upper lobe pulmonary opacity in elderly patients typically includes infectious or malignant causes.
• Unilateral lung edema, particularly due to cardiac issues, is a less common but critical consideration.

Observation:

• An 80-year-old afebrile patient presented with cough, dyspnea, and hemoptysis, showing an isolated right upper lobe infiltrate on chest X-ray.
• Further investigation with chest computed tomography (CT) and echocardiography was performed.

Findings:

• Chest CT revealed bilateral alveolar opacities and pleural effusions, not evident on initial X-ray.
• Echocardiography identified a flail posterior mitral valve leaflet with severe mitral regurgitation.

Implications:

• Pulmonary edema secondary to mitral valve regurgitation should be considered in elderly patients with unilateral lung infiltrates.
• Chest CT and echocardiography are key diagnostic tools for identifying heart failure-related pulmonary edema.
• Diuretic therapy can rapidly improve both radiologic and clinical manifestations of this condition.
