Figure 3.

Lipoma: 72-year-old female with history of soft tissue mass posterior to the left scapula. Axial T1W pre-contrast (a), T1W FS (b) and T1W FS post-gadolinium (c) images demonstrate a predominately fat-signal mass in the left posterior chest wall, between the rhomboid and trapezius muscles. Few thin internal septa are seen without nodularity. Heterogeneous enhancement is seen on post contrast images, greater than expected than with a conventional lipoma, which raised concern for an atypical lipomatous tumor or angiolipoma. H&E 20× (d). Corresponding pathology showed mature adipose tissue with uniform nuclei and no atypia, consistent with benign lipoma.
