In the T2-weighted sagittal image, the Achilles tendon (arrow) is partially torn horizontally just below the tibiotalar joint, and the tendon has thickened markedly just below the tear. A small amount of adipose tissue is interposed into the tear. Above that tear, the tendon is also torn vertically (short arrow) and has a high intensity signal (white). The vertical tear measures about 5 cm.
