Vanishing hemangiomas due to steatosis

Case contributed by Bálint Botz
Diagnosis almost certain


Screening US. Two small echogenic liver lesions known from last scan, two years earlier, confirmed as hemangiomas.

Patient Data

Age: 40 years
Gender: Female

The two small, stable lesions situated in segment 2 and 6 can be identified, although with much difficulty, even though the background echogenicity of the liver has increased only subtly due to steatosis. 

2 years earlier examination


Note that lesions are far more easily seen on the earlier images (same transducer and preset).

Case Discussion

Even very subtle increase in the echogenicity of the liver can obscure echogenic lesions such as typical hemangiomas. If the steatosis progresses further the lesions can "reappear" but as hypoechogenic lesions on the background of the fatty liver.
