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

From the case:
Vanishing hemangiomas due to steatosis
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/121844/annotated_viewer_json?c=1669532296\u0026lang=us"}
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.

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.
