“…Вместе с тем, Е. Kronzer и соавт. показали, что в отличие от тромба, СЛА имеет тенденцию занимать весь просвет с локальной аневризматической дилатацией и может образовывать характерные острые углы со стенкой сосуда [7]. Обнаружение подобного признака на КТ-ангиографии, названного "wall eclipsing", может помочь отличить СЛА от тромбоэмболического заболевания.…”

Pulmonary artery sarcoma (PAS) is a malignant and very rare tumor with frequent misdiagnosis. A rare clinical case with this pathology is presented. The patient had daily fever for 6 months, he was examined in various hospitals, but the cause of fever could not be determined. In our hospital, echocardiography revealed a mass in the left pulmonary artery (PA) with obstruction. CT-angiopulmonography showed a filling defect in the left PA, blocking the lumen of the artery by 90%. According to histopathology, the patient was diagnosed with pulmonary artery sarcoma. Subsequently, the following was performed: thrombendarterectomy from the pulmonary artery, combined pneumonectomy on the left side, suturing of the secondary atrial septal defect, followed by 3 courses of monochemotherapy with paclitaxel. After 1 year and 9 months, due to disease progression the patient died. The prognosis of PAS depends on early diagnosis, so doctors should be aware of this disease and use the best treatment options.

“…[38] This sign is defined as the presence of the following 3 findings: a low-density intraluminal mass of the pulmonary trunk, left pulmonary artery, or right pulmonary artery with near complete occlusion; proximal protrusion of the mass toward the right ventricular outflow tract; and eclipsing of 1 or both walls of the involved artery before the lesion infiltrates beyond the artery. [35,39] Therefore, the "wall eclipsing sign" on CTPA is considered to be the specific manifestation of pulmonary artery tumors. [35,[38][39][40] With this manifestation, it is possible to accurately differentiate PPATs from PE, which requires that both Radiologists and clinicians be familiar with the characteristics of this disease on CTPA, to improve the accuracy of the diagnosis.…”

Primary pulmonary artery tumors (PPATs), originating from the pulmonary artery intima, are rare tumors characterized by pulmonary artery luminal occlusion and pulmonary hypertension. Diagnosis of this rare entity is a challenging dilemma with the need for a high expertise in the radiological and pathological identification of PPATs. computed tomographic pulmonary angiography of PPATs may show filling defects, which are easily misdiagnosed. The radionuclide scan, along with other imaging examinations, can assist with the diagnosis, but the pathological diagnosis requires a puncture or surgical resection. Most primary pulmonary artery tumors are malignant, with poor prognosis and lack of specificity in clinical manifestations. However, there is no unified understanding and standard for diagnosis and treatment. In this review, we discuss the status, diagnosis, and treatment of primary pulmonary artery tumors, as well as how clinicians can better understand and treat the disease.

Background Primary pulmonary artery sarcoma (PAS) is an extremely rare malignant tumor with a poor prognosis. The clinical manifestations of PAS are diverse, including dyspnea, chest pain, cough, and hemoptysis. The poor prognosis is often due to delayed diagnosis caused by similarity in imaging findings with pulmonary thromboembolism (PTE). These cues of diagnosis include the “wall eclipsing sign”, lobulated bulging margins, gadolinium enhancement during MRI imaging, and FDG uptake during PET/CT imaging. However, there are still many misdiagnoses. Case presentation This article reports a woman of reproductive age presenting with a pulmonary artery mass. The computed tomographic pulmonary angiography and positron emission tomography/computed tomography did not show obvious signs of pulmonary artery sarcoma, however, contrast-enhanced echocardiography showed moderate perfusion, which helped differentiate between pulmonary artery sarcoma and pulmonary artery thrombosis, leading to timely surgical treatment. Conclusions PAS is a rare form of cancer that can occasionally be visually similar to PTE on radiographic images. Early diagnosis of PAS is of vital importance to the prognosis of the patients. There are several visual cues that can help differentiate between the two conditions. Additionally, contrast-enhanced echocardiography provides additional information on tumor perfusion, offering another effective approach for a prompt and accurate diagnosis.
