Abstract
Muscle variation may occur due to genetic or developmental causes. Some variations may compromise the vascular, muscular or nervous system in the region. Bilateral muscle variation in popliteal fossa is very rare. In present study an instance of bilateral muscle variation in popliteal fossa, arising from different muscles like gastrocnemius and from biceps femoris is recorded. There is no report of such variations. These observations are rare of its kind because of bilateral asymmetrical presence and difference in the origins in different legs. This is the first report as for the literatures available. Clinical and functional importance of such variation is discussed with the morphological aspects of this anomalous muscle.
