Intramuscular lipomatous tumor in a 45-year-old female patient in the left gluteus muscles. (a) The axial T1 weighted image with fat saturation (FS) and (b) the axial T2 weighted image show a well-defined lipomatous tumor which was classified as a lipoma after resection. Another 65-year-old male patient showed an intramuscular lipomatous tumor reaching into the subcutaneous region of the left shoulder. (c) An axial T2 weighted and a (d) coronal T2 weighted image demonstrating pseudo-infiltrative margins of the tumor, which was classified as an ALT after resection
