Figure 1c. Subcutaneous lipoma superior to the clavicle in a 32-year-old woman. (a, b) Coronal T1-weighted (repetition time msec/echo time msec= 583/30) (a) and T2-weighted (2580/80) (b) MR images show a mass that is isointense relative to subcutaneous fat (*). It is surrounded by a low-signal-intensity capsule (arrows), which allows it to be distinguished from adjacent adipose tissue. (c) Photograph of the sectioned gross specimen reveals diffuse fat throughout the lesion (*) and the surrounding capsule (arrowheads).
