The differential diagnosis of a left atrial mass on echocardiogram includes thrombus, vegetation, tumour, and other rare causes like septal aneurysm, pulmonary vein remnant, and septal haematoma. We present interesting echocardiographic images of a rare condition which can masquerade as a left atrial mass following cardiac surgery.

Hepatoblastoma is the most common malignant liver tumour in early childhood. The metastatic extension of hepatoblastoma into the left atrium via the pulmonary vein is rare. Reported lesions almost always involve a right-sided approach. Here we report the case of a 3-year-old girl with a recurrent hepatoblastoma at multiple sites, including the left atrium, brain, and lung. The patient was treated surgically for the prevention of further embolic complications and cardiac failure.

We describe a case of Candida endomyocarditis in a neonate not diagnosed until autopsy. Echocardiography had demonstrated a left atrial mass. Since cardiac candidiasis seems to be occuring with greater frequency in neonatal intensive care units, echocardiography and blood cultures should be done to exclude this previously rare event.
