Accessory muscles of the lower calf.

ABSTRACT

Two rare cases of accessory muscle of the lower calf observed in dissecting room cadavers are described here. This muscle is supposed to occur in 1% bodies and is implicated in tarsal tunnel syndrome. Occurrence of such anomalous muscles should be considered while examining cases reporting with pain associated with swelling in the region of Achilles tendon since they may mimic a soft tissue tumour.
