case_images: (a) T1-weighted Magnetic resonance image showing a well-defined hypointense lesion (arrow) superior to the distal end of the clavicle. (b) Well-defined lesion (arrow) showing short T1 inversion recovery hyperintensity. (c) Lesion (arrow) showing homogenous enhancement on postcontrast T1-weighted image. (d) Ultrasound grey scale and color Doppler images showing a well-defined, homogenously hypoechoic lesion (asterisk) with minimal intralesional vascularity (arrow)

case_images: T1 inversion recovery images [Figure 1b, arrow]. T1-weighted images [Figure 1c, arrow] and was superior to the distal end of the clavicle in the subcutaneous plane. There was no obvious communication of the lesion with either the acromioclavicular or glenohumeral joint. There was no erosion, remodeling, or sclerosis of the superior clavicular surface. The fat planes with all 14 surrounding structures were maintained. Correlative ultrasound revealed a well-defined, homogenously hypoechoic lesion [Figure 1d, asterisk] with minimal intralesional vascularity [Figure 1d, arrow].
