Biventricular 'salmon roe' lesions: Intracardiac metastasis from oral squamous cell carcinoma

摘要

A 43-year-old woman diagnosed with right lower gum squamous cell carcinoma (Stage IVb) presented to the emergency room with a symptom of progressive orthopnoea for 1 week. Two-dimensional echocardiography revealed massive pericardial effusion. An M-mode image showed a right ventricle collapse at the diastolic phase (Panel A, white arrow) compatible with cardiac tamponade.
