Male; 60 years old. Reason: 60 y/o M with PMH of SVT with likely lipoma on upper back, please ultrasound and evaluate On the right upper back at the site of the palpable abnormality is a 6.2 x 1.6 x 4.5 cm intramuscular, ovoid structure which is isoechoic to the adjacent muscle with thin internal striations that are parallel to the long axis of the structure itself. Portions of the border of this lesion are not easily discernible from the adjacent muscle. There is no internal vascularity seen on color Doppler.
6.2 x 1.6 x 4.5 cm intramuscular structure is most compatible with a lipoma. Other benign etiologies such as normal variant of the musculature are also considered.
