Click 68-year-old male with ankle pain and an accessory peroneocalcaneus internus muscle. Oblique axial proton density MRI of the right ankle performed at 3 Tesla (TR=3707, TE=29, ETL=8, FOV=14cm, slice thickness=4mm, slice spacing=0, FOV=14cm, matrix=384x256). A cutaneous marker on the lateral ankle marks the site of pain. The accessory peroneocalcaneus internus muscle is situated between the flexor hallucis longus muscle and the peroneus brevis muscle.

Click 68-year-old male with ankle pain and an accessory peroneocalcaneus internus muscle. Oblique coronal proton density MRI of the right ankle performed at 3 Tesla (TR=4946, TE=29, ETL=8, FOV=14cm, slice thickness=3mm, slice spacing=0, FOV=14cm, matrix=384x256). A cutaneous marker on the lateral ankle marks the site of pain. The accessory peroneocalcaneus internus tendon inserts upon a calcaneal tubercle immediately distal to the sustentaculum tali.
