Reason: evaluate non vascularize structure on RLE History: RLE abnormality A skin marker was placed along the posterior aspect of the right leg presumably corresponding to the patient's palpable area of concern. Note is made of a 3.1 x 2.4 cm mass within the lateral head of the gastrocnemius at the level of the myotendinous junction which corresponds to the findings on recent ultrasound examination. There is heterogeneous but predominantly low signal intensity on T1-weighted images with heterogeneous intermediate and increased signal intensity on T2-weighted images. There is apparent restricted diffusion within this lesion on diffusion-weighted images although some of this may, in part, represent T2 shine through. The tendon of the lateral head of the gastrocnemius appears intact. There is diffuse nonspecific subcutaneous edema most pronounced along the posterior, medial, and lateral aspect of the leg. There is also fluid signal intensity extending from the region of an apparent Baker's cyst which may represent the sequela of leakage or rupture of a Baker's cyst.
Nonspecific 3.1 cm mass in the lateral head of the gastrocnemius at the level of the myotendinous junction. There is associated restricted diffusion on diffusion-weighted images. This is incompletely characterized on this noncontrast examination, and could represent a soft tissue neoplasm, although hematoma formation and abscess remain as differential considerations.
