Introduction. Intimal sarcoma is a very rare tumor arising within the intima of the pulmonary artery. Preoperative diagnosis of pulmonary artery sarcoma is difficult, and the tumor is sometimes misdiagnosed as pulmonary thromboembolism. We report a case of pulmonary artery intimal sarcoma successfully diagnosed by preoperative endovascular biopsy and treated via right pneumonectomy and pulmonary arterioplasty. Presentation of a Case. A 72-year-old woman was referred to our hospital with a low-attenuation defect in the lumen of the right main pulmonary artery by computed tomography. Pulmonary artery thromboembolism was suspected, and anticoagulation therapy was administered. However, the defect in the pulmonary artery did not improve. Endovascular catheter aspiration biopsy was performed. Histological examination revealed pulmonary artery sarcoma. The patient was treated with right pneumonectomy and arterioplasty with the use of cardiopulmonary bypass. Discussion. Preoperative biopsy by endovascular catheter is worth considering for a patient with a tumor in the pulmonary artery and can help in planning treatment strategies.

A female patient in her 30s was referred to us with a mass approximately 8 centimeters in diameter in right lung segment 6. Bronchoscopy was done, and a tumorous lesion obstructing right B6 was found. Biopsy of this lesion supported suspicions of sarcoma or spindle cell carcinoma. Contrast-enhanced CT showed that the mass extended to and obstructed the right main pulmonary artery. A skip lesion was also suspected in the periphery of pulmonary artery trunk. The tumor was removed by right pneumonectomy accompanied by resection of the main and left pulmonary arteries under cardiopulmonary bypass. The pulmonary artery trunk and the left pulmonary artery were reconstructed with a vascular graft. Collectively, intimal sarcoma originating from the right main pulmonary artery with extension into the right lung was diagnosed. Significant extension of pulmonary artery sarcoma into the lung, as was observed in the present case, is considered to be rare, and to our knowledge this is the first report in which the primary lesion was biopsied by bronchoscopy.

Introduction. Sickle cell hemoglobin D disease (HbSD) is a rare variant of sickle cell disease (SCD). Incidence of pulmonary thromboembolism (PE) and deep venous thrombosis (DVT) in children with HbSD is unknown. PE and DVT are known complications of SCD in adults but have not been reported in the literature in children with HbSD.Case Report. We are reporting a case of a 12-year-old boy with HbSD with acute chest syndrome (ACS) complicated by complete thrombosis of the branch of the right pulmonary artery and multiple small pulmonary artery emboli seen on computed tomography (CT) pulmonary angiogram and thrombosis of the right brachial vein seen on Doppler ultrasound. Our patient responded to treatment with anticoagulant therapy.Conclusion. There are no cases reported in children with HbSD disease presenting as ACS with pulmonary thromboembolism. We suggest that PE should be suspected in patients presenting with ACS who do not show improvement with standard management. CT pulmonary angiogram should be utilized for early diagnosis and appropriate management as there is no current protocol for management of PE/DVT in pediatric patients with SCD.

Abstract Background: Pulmonary artery intimal sarcoma(PAS) is a very rare disease, the prevalence of it is about 0.001%-0.003%1. PAS is often misdiagnosed as acute or chronic pulmonary thromboembolism due to its clinical presentation and radiological findings. Thus early diagnosis is very crucial and may improve patient outcome.Case presentation: Here we report a case in a Chinese male which the symptom as presentation was episodes of shortness of breath. Transthoracic echocardiography showed a solid mass in the pulmonary valve orifice, which was demonstrated to be a pulmonary artery intimal sarcoma diagnosed by histopathology2. In this case the initial differential diagnosis included pulmonary embolism. Because the initial symptom of primary pulmonary artery sarcoma is extremely similiar to the pulmonary embolism. Half of them may be misdiagnosed as pulmonary embolism. Imaging studies are very helpful. Ultrasound and CT are the best due to their resolution and ability to assess the relationship of the mass with the surrounding structures. The final diagnosis is mostly made after surgical excision and this is the most effective treatment. At the same time, radiotherapy and chemotherapy after surgery is also a adjuvant treatment3.Conclusion: We report a very rare case of pulmonary artery intimal sarcoma, due to late diagnosis and delayed treatment in this case, the patient display a poor prognostic. Early diagnosis and right treatment can improve the prognosis of PAS and optimize overall health.

A 38-year-old man with a history of polyposis syndrome diagnosed 3 years previously, with poor compliance for follow-up, presented to the emergency department with symptoms of retrosternal chest pain associated with dizziness and shortness of breath. His blood pressure was 94/43 mm Hg, his pulse was 123 beats/min and he had an oxygen saturation of 84% on room air. The patient’s initial laboratory results showed a hemoglobin of 80 g/L and blood gas with a pH of 7.23. He had a normal chest radiograph and electrocardiogram, but had an elevated troponin I at 0.12 μg/L. He was given acetylsalicylic acid for suspicion of acute coronary syndrome. On physical examination, the patient was found to have right calf tenderness. With this finding and the presenting symptoms, he underwent computed tomography angiography (CTA) of the chest. The chest CTA showed a massive saddle embolus with a filling defect completely occluding the right pulmonary artery and extending through the main pulmonary artery segment to involve the left pulmonary artery. There were also diffuse filling defects involving bilateral pulmonary segmental arteries (Fig. 1 and Fig. 2). The patient received alteplase and underwent a workup for a hypercoagulable state. His workup revealed positive anticardiolipin antibodies and factor V Leiden. The Doppler ultrasound of his lower extremities showed an extensive thrombus measuring more than 6 cm extending in the right superficial femoral vein. The patient was then referred for placement of an inferior vena cava filter.
