Clinical introduction A 63-year-old woman recently diagnosed with lung metastasis, after routine chest radiography, was admitted to our hospital for unspecified symptoms, such as dyspnoea on minimal exertion and dry cough. Physical examination showed uncommon signs. The electrocardiogram showed sinus rhythm and incomplete left bundle branch block. Thoracic CT scan revealed bilateral lung and pleural metastases and pelvic CT showed a right femoral bone mass. Transthoracic echocardiography revealed a heterogeneous mass, lateral to the right ventricle, with pericardial effusion. Further, cardiac MRI (cMRI) was performed (figure 1A,B). Diagnosis was completed with an ultrasound-guided biopsy and histopathological examination (figure 1C,D).
Question Which of the following is the most likely diagnosis?
Secondary malignant cardiac tumour.
- cardiac magnetic resonance (CMR) imaging
- pericardial effusion
- pericardial tamponade
- palliative care
- cardiac computer tomographic (CT) imaging
