A 52-year-old woman was referred to the respiratory team with worsening shortness of breath for the last 3 months, which had deteriorated significantly over the last 2–3 weeks. She underwent a CT pulmonary angiogram, which was reported locally as showing a large pulmonary embolism. Given the chronic history and appearance of the thrombus, the patient was referred to a specialist pulmonary vascular disease multidisciplinary team and underwent a PET-CT scan with the diagnosis being felt to be more consistent with a pulmonary artery sarcoma. Within 4 weeks, she underwent a pulmonary endarterectomy which confirmed the presence of an extensive mass. She underwent bilateral endarterectomy and pulmonary artery valve replacement, with subsequent improvement of her breathlessness back to premorbid baseline. Postoperative histology has confirmed a pulmonary artery angiosarcoma. Alternate imaging modalities and early referral to a specialist unit allowed as early a diagnosis as possible with good symptomatic benefit.

Chronic Thromboembolic Disease

A 29-year-old female patient presented with chest pain, breathlessness and syncope on the background of constitutional symptoms, oral ulceration and a rash. Multiple investigations were performed, including a CT pulmonary angiogram (CTPA) that was initially felt to show imaging features consistent with a diagnosis of chronic thromboembolic disease (CTED). The patient was referred to a tertiary pulmonary hypertension centre and the possibility of pulmonary vasculitis was raised. Subsequent positron emission tomography (PET)-CT revealed imaging features supporting this diagnosis. The patient was treated with intravenous cyclophosphamide infusions, following which her symptoms improved. A repeat PET-CT 6 months after treatment showed resolution in pulmonary artery and mediastinal uptake, but persistence of pulmonary artery occlusions on a repeat CTPA. A final diagnosis of pulmonary vasculitis secondary to Behçet’s disease was made. This case report aims to raise awareness of the imaging features of CTED and its mimics.

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.
