Left ventricular "diverticulum" in a patient affected by galactosialidosis.

We present the case of a 35-year-old man affected by the late juvenile form of galactosialidosis. He was known for a moderate pericardial effusion which remained unchanged in the last 12 months. Last follow-up transthoracic echocardiographic examination showed a bulging of the posterior and lateral wall of the left ventricle. This finding has never been described before in galactosialidosis.
