ABSTRACT: Plantaris is considered as vestigial muscle in human with a small belly and long thin tendon. It is known to present several anatomical variations in terms of its occurrence, origin, course, relation with surrounding neurovascular structures and insertion. It may be absent unilaterally or bilaterally. On rare occasion, its double occurrence has been reported also. One such variation was observed unilaterally in the present report in which variant origin with two distinct heads of the muscle were seen to be merged to form a common long tendon that passed deep to both heads of gastrocnemius and soleus before final insertion into flexor retinaculum of ankle. Despite its vestigial nature, injury to plantaris muscle can present diagnostic challenge among clinicians and radiologists. Surgical importance of the muscle lies in successful use of its tendon for reconstructive surgery. Therefore, knowledge of possible variations regarding plantaris muscle is important.

KEY WORDS: Plantaris, Vestigial, Additional head, Flexor retinaculum.
