Fig. 1A. —29-year-old woman with mass in anterolateral soft tissues of
right ankle who presented with increasing pain of 3 months' duration.
Longitudinal sonogram shows anechoic mass within subcutaneous tissue. No
communication with joint or tendon sheath was identified. Posterior acoustic
enhancement (arrowheads) can be seen. Reverberation artifact is
visible at superficial border of cyst (small arrows). Large arrow =
ganglion cyst.

Fig. 1B. —29-year-old woman with mass in anterolateral soft tissues of
right ankle who presented with increasing pain of 3 months' duration.
Photomicrograph of ganglionic cyst shows dense fibrous wall (arrows)
surrounding well-defined central cavity (asterisk). (H and E,
x2)

Fig. 2B. —48-year-old woman with mass in lateral soft tissues of ankle.
Photomicrograph of mass shows portion of dense fibrous wall
(arrowheads) with myxoid degeneration (arrows) that
surrounds central cystic cavity (asterisk). (H and E, x10)

Fig. 3A. —47-year-old woman with mass in medial soft tissues of right
ankle who presented with progressive pain and swelling over 7 months.
Longitudinal sonogram shows anechoic mass (arrows) superficial to
posterior tibial tendon (small arrowheads) and flexor digitorum
longus tendon (large arrowhead).

Fig. 3B. —47-year-old woman with mass in medial soft tissues of right
ankle who presented with progressive pain and swelling over 7 months.
Transverse sonogram shows anechoic mass (arrows) with lobulation,
extending between posterior tibial tendon (small arrowheads) and
flexor digitorum longus tendon (large arrowhead).

Fig. 4A. —42-year-old woman with mass on dorsal ankle. Longitudinal
sonogram shows mass (arrows) judged to be hypoechoic relative to
surrounding muscle by consensus review. Posterior acoustic enhancement is
noted as increased hyperechogenicity of talar cortex (arrowheads).
Two split screens were aligned for extended field of view in this image. tib =
tibial cortex, talus = talar cortex.

Fig. 4B. —42-year-old woman with mass on dorsal ankle. Transverse
sonogram shows hypoechoic mass with communication (straight arrows)
extending toward lateral subtalar joint (curved arrow) between talus
(tal) and calcaneus (cal).

with multiple internal septations (arrows).

Fig. 5B. —32-year-old woman with mass in anterolateral soft tissues of
ankle. Transverse sonogram shows mass (large straight arrows) with
prominent thick septation (small straight arrow). Echogenic component
(curved arrow) can be seen along deep border, which is consistent
with dependent debris. TRANSV = transverse, MED = medial aspect of mass.
