63-year-old male with an upper extremity mass. Evaluate for soft tissue mass/possible lipoma. There is a marker along the anterior aspect of the arm at the level of the mid humeral diaphysis. There is slight prominence of the fat immediately medial to the marker which may represent a lipoma, but this is equivocal. A second marker was placed more distally along the medial aspect of the arm, approximately 4 cm above the level of the medial epicondyle. Once again, there is slight prominence of the subcutaneous fat proximal to this marker, which could represent a lipoma. Measurements of the aforementioned fatty prominences is limited due to the lack of inherent contrast with the surrounding fat. We see no mass or signal abnormality within the underlying musculature. The bone marrow signal intensity is within normal limits. Mild osteoarthritis affects the acromioclavicular joint. Degenerative disc disease affects the visualized thoracic and lumbar spine.
Mild prominence of the subcutaneous fat as described above which may represent subcutaneous lipomas. We otherwise see no soft tissue abnormality.
