Cardiac amyloidosis secondary to multiple myeloma

We report a case of a 51-year-old Caucasian man with progressive heart failure and multiple lytic lesions in the skull and long bones. The diagnosis of multiple myeloma and cardiac involvement by secondary amyloidosis was made, but the patient died despite treatment, and the diagnosis was confirmed at autopsy. Cardiac amyloidosis is clinically silent and when the symptoms appear, median survival is less than 1 year. The diagnosis of amyloidosis should be considered in any patient with multiple myeloma and heart failure, and the magnetic resonance imaging (MRI) can help to make this diagnosis.
