Computed tomography findings of pathologically proven pulmonary infarction associated with bronchogenic carcinoma are reported for two patients. In one case, the infarction was demonstrated as a well-defined pleura-based large nodule in the peripheral portion of the same lobe of the tumor. The nodule had a smooth, convex border and a linear strand from the apex of the lesion toward the hilum. The obstruction of the subsegmental pulmonary artery due to tumor invasion was considered the cause of pulmonary infarction. In the second case, the infarction was demonstrated as a rapidly appeared, pleura-based consolidation in the same lobe of the tumor with a blurred border. Obstruction of the pulmonary vein by a tumor might have played an important role in the development of the pulmonary infarction in association with a large pulmonary artery obstruction. We conclude that pulmonary infarction should be considered as a differential diagnosis when peripheral pulmonary nodules or masses are located in the same lobe as the primary cancer.

Since large-scale reports of pulmonary infarction in systemic lupus erythematosus (SLE) are limited, a retrospective study was performed for this manifestation in 773 hospitalized patients in southern Taiwan from 1999 to 2009. Pulmonary infarction was defined as the presence of pulmonary embolism, persistent pulmonary infiltrates, and characteristic clinical symptoms. Demographic, clinical, laboratory, and radiological images data were analyzed. There were 12 patients with pulmonary embolism and 9 of them had antiphospholipid syndrome (APS). Six patients (19 to 53 years, average 38.2 ± 12.6) with 9 episodes of lung infarction were identified. All cases were APS and four episodes had coincidental venous thromboembolism. There were four episodes of bilateral infarction and seven episodes of larger central pulmonary artery embolism. Heparin therapy was routinely prescribed and thrombolytic agents were added in two episodes. Successful recovery was noted in all patients. In conclusion, there was a 0.8% incidence of pulmonary infarction in patients with SLE, all with the risk factor of APS. Differentiation between pulmonary infarction and pneumonia in lupus patients should be made; they have similar chest radiography with lung consolidation but require a different clinical approach in management. Although this report is a retrospective study with relatively small numbers of lupus patients with lung infarcts, our observation might provide beneficial information on the clinical features and radiological presentations during the disease evolution of pulmonary infarction in SLE with APS.

UNLABELLED
A patient initially treated with corticosteroids for cryptogenic organising pneumonia following pulmonary infarction, developed a worsening condition with progressive cavitary formations in both lower lung lobes. Contrast-enhanced chest computed tomography revealed a pulmonary embolism, and serum anti-Aspergillus IgG antibody analysis yielded a strong positive result. Consequently, the patient was diagnosed with pulmonary infarction with Aspergillus infection; organising pneumonia in surrounding areas reflected the repair process. Following treatment with anticoagulants and antifungal agents, the patient was successfully discharged. Hence, pulmonary infarction should be considered in cases of refractory lung lesions.
LEARNING POINTS
Pulmonary infarction should be considered in case of refractory lung lesions, even if the patient does not have the risk of embolism.Organising pneumonia should be assessed carefully because it may occur as a repair process of various lung diseases.

Pulmonary vein stenosis is a rare condition that is often underdiagnosed and misdiagnosed. The clinical and radiologic manifestations are unspecific such as cough, hemoptysis and pulmonary lesions and are therefore difficult to distinguished with pneumonia and tuberculosis. The present study is a successful case report of pulmonary vein stenosis and pulmonary infraction secondary to mediastinal seminoma. This case suggested that pulmonary vein stenosis should be considered when a mediastinal mass is accompanied by pulmonary opacites that cannot be explained by common causes such as infection.

A 67-year-old woman with rheumatoid arthritis (RA) presented with fever and dyspnea. Chest radiography and computed tomography (CT) revealed pulmonary infiltrates with ground-glass opacities. We considered bacterial or pneumocystis pneumonia because she was immunocompromised due to RA treatment. However, she had tachycardia and elevated D-dimer levels. We performed contrast-enhanced CT and subsequently diagnosed her with pulmonary embolism (PE). Though PE is not usually accompanied by parenchymal pulmonary shadows, pulmonary infarction may cause pulmonary infiltrates that can be mistaken for pneumonia. As RA is a thrombophilic disease, clinicians should be aware of PE and pneumonia as differential diagnoses in such patients.

Observational Study
OBJECTIVE
This study aimed to describe pulmonary high-resolution CT (HRCT) findings in Takayasu arteritis (TA) and to determine possible causes.
METHODS
A total of 243 TA patients were enrolled from a prospective cohort after excluding patients with other pulmonary disorders or incomplete data. Patients were divided into two groups: those with normal lung HRCT and those with abnormal lung HRCT. Clinical characteristics were compared between groups and binary logistic regression analysis was applied to identify possible causes of the lung lesions. Follow-up HRCT (obtained in 64 patients) was analysed to study changes in pulmonary lesions after treatment.
RESULTS
Of the 243 patients, 107 (44.0%) had normal lung HRCT while 136 (56.0%) had abnormal lung HRCT, including stripe opacity (60.3%), nodules (44.9%), patchy opacity (25.0%), pleural thickening (15.4%), pleural effusion (10.3%), ground-glass opacity (8.1%), pulmonary infarction (6.6%), mosaic attenuation (4.4%), bronchiectasis (3.7%) and pulmonary oedema (2.2%). Patients with abnormal HRCT were significantly more likely to have type II arterial involvement (25% vs 12.2%, P = 0.04), pulmonary arterial involvement (PAI; 21.3% vs 5.6%, P < 0.001), pulmonary hypertension (20.6% vs 8.4%, P = 0.01) and abnormal heart function (27.9% vs 7.6%, P < 0.001). Logistic regression analysis demonstrated that PAI, worsened heart function and age were associated with presence of pulmonary lesions. Pulmonary infarction, pleural effusion and patchy opacities improved partially after treatment.
CONCLUSION
Pulmonary lesions are not rare in patients with TA. Age, PAI and worsened heart function are potential risk factors for presence of pulmonary lesions in TA.

Lung infarction after intrathoracic surgery is a life-threatening complication that needs urgent intervention. Although the exact etiology is not known, pulmonary infarction may be suspected for patients presenting with consolidation of the lung after intrathoracic surgery. We report a very rare case of pulmonary infarction after successful surgical treatment of a type B aortic dissection. The pulmonary infarction was treated by intrapericardial pneumonectomy. This article discusses possible etiology and management of such patients. A high index of clinical suspicion and timely investigations may allow early detection of this unusual event and avoid fatal outcomes.

UNLABELLED
The main ultrasound criterion for diagnosing pulmonary infarction is the presence of triangular/wedge-shaped or rounded, hypoechogenic, homogeneous, pleura-based lesions. When used in point-of-care, ultrasonography of several organs can facilitate the diagnosis of pulmonary embolism in a patient presenting with chest pain. We describe a case of chest pain which we thought was due to angina, but point-of-care ultrasonography directed us to a diagnosis of pulmonary embolism.
LEARNING POINTS
Point-of-care ultrasonography can help the clinician make a rapid diagnosis in patients with acute respiratory failure.The main ultrasound criterion for diagnosing pulmonary infarction is the presence of triangular/wedge-shaped or rounded, hypoechogenic, pleura-based lesions.
