1/164. pulmonary artery fibrous bands: report of a case with extensive lung infarction and superinfection with coccidioides immitis, pseudomonas, and acid-fast bacilli.

    A 46-year-old woman presented with shortness of breath and frequent lower respiratory tract infections. A ventilation-perfusion scan showed markedly reduced perfusion of the right lung, and pulmonary arteriogram showed stenosis of the right pulmonary artery. A right pneumonectomy revealed dense white fibrous bands partially occluding the pulmonary artery branches and two large abscess cavities filled with pus in the upper and lower lobes. Microscopic examination revealed extensive necrosis of lung parenchyma, suppurative granulomatous inflammation with coccidioides immitis organisms and rare acid-fast bacilli. pulmonary artery fibrous bands were originally believed to be congenital; however, they are now known to be sequelae of thromboembolic phenomena.

2/164. Pulmonary bone marrow embolism in sickle cell disease.

    We report an unusual lethal complication of sickle cell anemia. The patient was admitted with a diagnosis of acute chest syndrome and died shortly after that of respiratory failure. autopsy revealed numerous deposits of bone marrow hematopoietic tissue occluding the microvascular circulation of the lung. Many causes of acute chest syndrome in sickle cell anemia have been identified, including bone marrow infarction leading to embolism of bone marrow fat. However, the release of bone marrow hematopoietic tissue leading to pulmonary vascular occlusion is not generally recognized premortem by treating physicians.

3/164. Flitting radiographic shadows: an unusual presentation of cancer in the lungs.

    Tumour involvement of pulmonary blood vessels occurs frequently in advanced lung cancer and occasionally may cause pulmonary infarction. A case is reported of diffuse obstruction of pulmonary arteries by cancer in which no primary tumour was found, and which presented as flitting radiographic opacities due to pulmonary infarction.

4/164. Pulmonary tumor embolism presenting as infarcts on computed tomography.

    Pulmonary tumor embolism is a rare cause of respiratory failure in patients with cancer and is only infrequently diagnosed during life. Chest radiographs are usually normal. Dilated and beaded peripheral pulmonary arteries may be present on computed tomography scans. The authors describe an unusual case of pulmonary tumor embolism presenting on computed tomography scans as bilateral, peripheral, wedge-shaped opacities. On autopsy, these opacities corresponded to areas of pulmonary infarction.

5/164. pulmonary embolism caused by acrylic cement: a rare complication of percutaneous vertebroplasty.

    A pulmonary embolus of acrylic cement was present in a 41-year-old woman with Langerhans' cell vertebral histiocytosis (LCH) after percutaneous vertebroplasty. Chest radiograph and CT confirmed pulmonary infarction and the presence of cement in the pulmonary arteries. She was treated with anticoagulants, and responded favorably. This rare complication occurred because perivertebral venous migration was not recognized during vertebroplasty. Adequate preparation of cement and biplane fluoroscopy are recommended for vertebroplasty.

6/164. pulmonary embolism mimicking acute myocardial infarction.

    pulmonary embolism is a major cause of death in the united states. A high index of suspicion is required to achieve an accurate diagnosis. We report a case of a patient with syncope, ischemic electrocardiographic changes, and an elevated troponin i level, presenting just like acute myocardial infarction. The case highlights the value of an early use of 2-dimensional echocardiography in obtaining an accurate diagnosis, thus avoiding unnecessary and inappropriate treatment.

7/164. lung metastases manifesting as pulmonary infarction by mucin and tumor embolization: radiographic, high-resolution CT, and pathologic findings.

    We present a case of lung metastasis manifesting as lung infarction by mucin and tumor embolization. The radiograph and high-resolution CT showed multiple focal consolidations with ground glass attenuation in subpleural areas of both lungs. diagnosis was made by open lung biopsy, which revealed pulmonary infarction caused by intravascular adenocarcinoma with numerous mucus emboli in pulmonary arteries. Subpleurally located consolidations on high-resolution CT correlated well with the histologic findings of lung infarction by mucin and tumor emboli.

8/164. Thrombotic pulmonary arteriopathy in polycythemia vera.

    pulmonary infarction and hemorrhage are important differential diagnoses in pulmonary coin lesions, especially in patients with underlying hematologic malignancies. We report a 58-year-old female patient suffering from polycythemia vera presenting with multiple pulmonary coin lesions. Open lung biopsy and subsequent histologic investigations showed organized pulmonary infarction and primary pulmonary thrombotic arteriopathy. Although histologic features are non-contributory in distinguishing organized thrombosis from organized thromboembolism, the clinical setting and localization of the lesions suggest that in the present case the vascular lesions are due to organized thrombosis.

9/164. pneumopericardium mimicking acute myocardial ischemia after laparoscopic cholecystectomy.

    pneumopericardium occurred after laparoscopic cholecystectomy in a 57-year-old woman. The patient had chest pain accompanied by T-wave inversion on electrocardiogram, with signs and symptoms suggestive of acute myocardial ischemia. Evaluation for myocardial infarction, however, was negative and clinical findings resolved spontaneously. Although pneumopericardium after laparoscopic procedures has been previously reported, this case illustrates how associated findings may mimic those of acute myocardial ischemia or infarction.

10/164. Pulmonary tumor embolism from primary cardiac B-cell lymphoma.

    We report the case of a 54-year-old man with pulmonary embolism during convalescence from "idiopathic" pericarditis. A transthoracic echocardiographic examination indicated a large mass within the right atrium. Subsequently, he died from refractory hypotension. On autopsy, two large whitish nodules were found in the right atrium; there was also nodular epicardial infiltration. Both lungs showed multiple, grossly visible tumor emboli with pulmonary infarction and no evidence of conventional thromboembolism. This is the first report of pulmonary tumor embolism due to large cell B-cell primary cardiac lymphoma. Refractory unexplained pericardial effusion, pulmonary embolism without risk factors for venous thrombosis, and/or the existence of a mass in the right heart should arouse clinical suspicion for this rare malignancy.
