Hepatic angiomyolipoma: demonstration by out of phase MRI

Hepatic angiomyolipoma is a rare liver pathology. In this case report, we describe MRI features of a hepatic angiomyolipoma with a high fat content, which was indeterminate on CT. In phase and out of phase T1-weighted spoiled gradient echo technique, T2-weighted fat suppressed fast spin echo technique and dynamic enhanced T1-weighted in phase gradient echo technique were used. Out of phase gradient echo sequence was the most sensitive technique identifying the fat content of the lesion in its mixed tissue composition.
