Primary Cardiac Angiosarcoma: A Rare and Fatal Diagnosis

Cardiac angiosarcoma with lung metastasis presented with multiple halo signs: One case report and literature review

Cardiac angiosarcoma is a rare aggressive malignancy with rapid progress and poor prognosis. Here we report 1 patient with cardiac angiosarcoma with lung metastasis, which presented as multiple halo signs and ground glass opacities. The patient underwent computed tomography (CT) guided lung biopsy and postoperative tissue histology confirmed the diagnosis of angiosarcoma. Transthoracic echocardiography (TTE) and cardiac Magnetic Resonance Imaging (MRI) identified the main tumor in the right atrium. Positron emission tomography/computed tomography (PET/CT) excluded intraabdominal lesions. The patient was given chemotherapy with nab-paclitaxel, cardiac radiation therapy and remained follow-up. Considering the rapid disease progression and poor prognosis, the present case report is intended to provide diagnostic insight into cardiac angiosarcoma with lung metastasis, especially with lung CT scans of multiple halo signs and ground glass opacities.

Primary cardiac angiosarcoma presenting with haemoptysis

A male patient in his 30s presented to the emergency room with a 1-week history of dyspnoea that progressed to haemoptysis, having coughed up approximately 200 mL of blood on two occasions. On diagnostic investigation, a mediastinal tumour infiltrating the free wall of the right atrium and multiple pulmonary nodules were discovered. The first suspicion was a neoplasm of pulmonary origin, and a bronchoscopy was performed, histology reported a probable cardiac origin for the neoplasm. A subsequent biopsy confirmed the presence of a primary cardiac angiosarcoma. An extension CT scan revealed brain metastases. The patient received chemotherapy treatment, resulting in a partial response to date. This case is one of the few reported instances of cardiac neoplasm presenting with respiratory symptoms.

Case report: Primary cardiac angiosarcoma with multiple metastases

This reports outlines a rare case of primary right atrial angiosarcoma with multiple metastases. Multimodality imaging and histopathology confirmed the diagnosis of primary cardiac angiosarcoma and multiple metastases. We present the details of the presentation, multimodality imaging findings, and clinical management. The patient was followed up by cardiac MRI (CMRI) 2 months after therapy, the cardiac tumor and pulmonary metastases decreased markedly. Up to now, the patient has undergone four cycles of chemotherapy and immunotherapy.
