Long axis scan along Lt. adductor pollicis m.
1. Adductor pollicis t.
2. 1st interossei mm.
3. 2nd finger flexor t.
4. Lumbrical m.
MC. Metacarpal bones
Lt. adductor pllicis muscle is diffusely swollen and mixed-echo mass is seen, but not clearly demarcated.

Compared to the Rt. Side, mixed echogenic lesion is located within Lt. adductor pollicis muscle(1) and shows high echoic change(*) under the lubrical muscle(L).
