Presence of third head of the gastrocnemius also known as caput tertium gastrocnemius can cause severe clinical complications as it may compress the popliteal vessels and nerves of the popliteal region. An early diagnosis of such incidence is of great importance in order to avoid vascular complications and to aid in the early rehabilitation. Sural nerve is a peripheral sensory nerve often used for several therapeutic and diagnostic purposes. Hence its formation and course in the calf assumes great significance. We report here a case with concurrent variations of gastrocnemius and the sural nerve. The gastrocnemius muscle originated with 3 heads. The additional third head took origin from lateral condyle of the femur and then merged with the medial head. The sural nerve took origin from the tibial nerve, passed through the line of union between the medial and third head of the gastrocnemius muscle.
