18 year old male with a small mass for 9 months also seen on recent ultrasound examination. A marker was placed along the volar and medial aspect of the mid to distal forearm at the site of the palpable abnormality. We suspect that there is a small subcutaneous fatty mass deep to the marker that measures no more than 8 mm in the greatest transverse dimension and approximately 1.5 cm in the longitudinal dimension, however, accurate measurement is difficult to obtain due to lack of inherent contrast with the surrounding subcutaneous fat. There is no enhancement of this mass or the surrounding area. We see no additional masses. The signal intensity of the musculature of the forearm is normal. The bone marrow signal intensity is normal.
Small subcutaneous lipoma of the left forearm.
