Abstract
Convex-probe endobronchial ultrasound (CP-EBUS) identified a vascularised 30 mm lesion, along the right pulmonary vein extending into the LA (figure 2). Needle aspiration was performed to the described mass and to the subcarinal lymph node. Both biopsies results were positive for lung adenocarcinoma, immunohistochemistry showed positive thyroid transcription factor-1(TTF-1), molecular analysis demonstrated a negative epidermal growth factor receptor (EGFR) and echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK). The patient started chemotherapy, anticoagulation and localised radiotherapy in her right hip. Cardiac metastasis of lung cancer usually involves the pericardium or epicardium by direct invasion and/or lymphatic spread, however metastasis to the LA myocardium and endocardium are extremely rare.1 Lesions in the LA and proximal portions of great arteries can be visualised by CP-EBUS.
