Ct findings 6.1x3.7x2.1cm intramuscular lipomatous gastrocnemius mass. likely lipoma. mri advised. was told do nothing unless worsens.i'm concerned?

Get MRI to be sure: MRI is better than CT to characterize soft tissue masses. IV contrast would likely be used for lipoma analysis. These statements assume the patient is a candidate for MRI and contrast. Lipomas are benign, but it is nice to almost completely exclude a rare liposarcoma--less than 3 in a million people diagnosed in a year. MRI along with a benign history and presentation does this.
