Massive hepatic cyst presenting as right-sided heart failure.

A 70-year-old woman presented with clinical features of right heart failure. Cardiopulmonary investigations included an echocardiogram, which showed a hepatic cyst compromising venous return and affecting right atrial filling and a CT abdomen showed a 15.5 × 11.5 cm-cystic mass involving the right hepatic lobe and compressing the right atrium. Percutaneous drainage of the cyst was performed. This led to complete resolution of symptoms but these recurred as the fluid re-accumulated. Subsequent definitive treatment with excision of the cyst was undertaken with symptomatic cure. This case is the first report of a hepatic cyst presenting as right heart due to compression of the right atrium.
