| Case | | |
A 47-year-old woman dancer presented with right lateral heel edema and pain with a numbness sensation. The range of motion of her right ankle was normal. She had not previously undergone any surgery on the affected ankle. The physical examination revealed a right lateral heel mass at the posterior talus–calcaneus junction. The mass was characterized by a mild numbness sensation upon palpitation, which radiated to the lateral heel and foot. She underwent an ultrasound examination [Figure 1]. [Figure 1]a was obtained by placing the transducer between the peroneus muscle and Achilles, where the small saphenous vein and sural nerve are present. The subsequent ultrasound image revealed the long and short axis of a portion of the sural nerve [Figure 1]b and [Figure 1]c. Magnetic resonance imaging was performed for further evaluation and localization [Figure 2]. | Figure 1: (a) Was obtained by placing the transducer between the peroneus muscle and Achilles tendon where small saphenous vein and sural nerve just there. (b and c) are ultrasound images of the long axis and short axis of part of the sural nerve. SSV: Small saphenous vein, PL: Peroneus longus muscle, PB: Peroneus brevis muscle
