The magnetic resonance imaging appearances of multiple actinomycotic liver abscesses are described. The abscesses appeared hypointense to liver parenchyma on T1-weighted sequences and hyperintense on T2-weighted sequences with some surrounding edema. Following intravenous gadolinium diethylenetriamine-pentaacetic acid, the masses showed a thick enhancing rim but no central enhancement. Although no etiology was discovered in the initial clinical history, antecedent dental surgery was evident on abdominal radiography that depicted dental amalgam in the ascending colon.
