“…Leukocytosis has previously been reported in patients with UPE resulting from severe MR in the absence of proven infection. 3,7,8,22 The association of unilateral pulmonary infiltrates and/or leukocytosis and/or acute respiratory distress led to the initiation of antibiotic therapy, usually in the absence of fever. This may delay therapeutic management of UPE; initiation of appropriate treatment was delayed in 33% of our UPE cases versus 4% in patients without UPE (Pϭ0.003), highlighting the difficulty of immediately making the correct diagnosis of UPE.…”

“…The unilateral location of cardiogenic pulmonary edema is unusual [3][4][5][6][7][8] and has rarely been described and mainly reported in association with severe mitral regurgitation (MR). 9,10 Little is known about the characteristics of unilateral pulmonary edema (UPE), and its prevalence has never been assessed in a large series of pulmonary edema.…”

Background-Cardiogenic unilateral pulmonary edema (UPE) is a rare entity, frequently leading to initial misdiagnosis.We sought to assess the prevalence of UPE and to determine its impact on prognosis compared with bilateral pulmonary edema. Methods and Results-We studied the characteristics and outcomes of patients admitted to our institution for cardiogenic pulmonary edema during an 8-year period. The study population included 869 consecutive patients. The prevalence of UPE was 2.1%: 16 right-sided UPE (89%) and 2 left-sided UPE (11%). In patients with UPE, blood pressure was significantly lower (PՅ0.01), whereas noninvasive or invasive ventilation and catecholamines were used more frequently (Pϭ0.0004 and PϽ0.0001, respectively). The prevalence of severe mitral regurgitation in patients with bilateral pulmonary edema and UPE was 6% and 100%, respectively (PϽ0.0001). In patients with UPE, use of antibiotic therapy and delay in treatment were significantly higher (PϽ0.0001 and Pϭ0.003, respectively). In-hospital mortality was 9%: 39% for UPE versus 8% for bilateral pulmonary edema (odds ratio, 6.9; 95% confidence interval, 2.6 to 18; PϽ0.001). In multivariate analysis, unilateral location of pulmonary edema was independently related to death whatever the model used (adjusted odds ratio, 6.5; 95% confidence interval, 1.3 to 32; Pϭ0.021 for model A; and adjusted odds ratio, 6.8; 95% confidence interval, 1.1 to 41; Pϭ0.037 for model B). Conclusions-Unilateral pulmonary edema represented 2.1% of cardiogenic pulmonary edema in our study, usually appeared as an opacity involving the right lung, and was always associated with severe mitral regurgitation. Unilateral pulmonary edema is related to an independent increased risk of mortality and should be promptly recognized to avoid delays in treatment. (Circulation. 2010;122:1109-1115.)

An unusual masquerade of community acquired pneumonia: Left-side unilateral pulmonary edema

The diagnosis of pneumonia is clinical, based on the history of lower respiratory tract symptoms, physical, and/or radiographic signs of consolidation. Several diseases such as congestive heart failure, pulmonary embolism, and chemical pneumonitis may present with similar symptoms, signs, and chest radiographs, thus delaying the definitive diagnosis and initiation of appropriate treatment. Unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first as a focal lung disease. We have presented an unusual case of left-sided UPE in a 76-year-old man who developed acute heart failure resulting from dietary and pharmacological noncompliance. The patient was successfully managed with decongestive therapy and non-invasive mechanical ventilation.

“…It has been reported after congestive heart failure, prolonged rest on one side in patients with cardiac decompensation or receiving large amounts of fluids, in cases of rapid expansion of the lungs after pleural effusion and pneumothorax; it is also seen in the normal lung in patients with unilateral pulmonary disease such as MacLeod syndrome and unilateral pulmonary artery hypoplasia or agenesis, pulmonary artery compression from aortic dissection or left ventricular pseudoaneurysm and pulmonary venous obstruction from mediastinal fibrosis. However, it is mainly reported in association with severe MR (1-4). …”

Unilateral Pulmonary Edema: A Rare Initial Presentation of Cardiogenic Shock due to Acute Myocardial Infarction

et al. 2012

Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first. Most cases of cardiogenic UPE occur in the right upper lobe and are caused by severe mitral regurgitation (MR). We present an unusual case of right-sided UPE in a patient with cardiogenic shock due to acute myocardial infarction (AMI) without severe MR. The patient was successfully treated by percutaneous coronary intervention and medical therapy for heart failure. Follow-up chest Radiography showed complete resolution of the UPE. This case reminds us that AMI can present as UPE even in patients without severe MR or any preexisting pulmonary disease affecting the vasculature or parenchyma of the lung.
