Large thymoma mass invading cardiac structures

Description

We report a retired, Afro-Caribbean man aged 69 years who presented to his local hospital with several weeks of dyspnoea and cough. Physical examination was unremarkable apart from an elevated jugular venous pressure and a bilateral pedal oedema. His medical history included asthma and controlled hypertension. Urgent transthoracic echocardiography showed a large soft tissue mass in the pericardial space compressing the right ventricle (RV), and the right atrium (RA).

A CT of the thorax showed a mass measuring 16 cm in width by 8 cm in depth with infiltration and compression of RV and RA with distortion of atrioventricular groove anatomy between RV and RA (figure 1).
