The current cadaveric report aims to present a coexistence of two uncommon variants of the posterior leg compartment. The variations were detected, during classical dissection in an 84-year-old donated male cadaver. On the left lower limb, the gastrocnemius muscle was identified as having a third head that was attached to the lateral head. This variant is known as gastrocnemius tertius muscle and was bilaterally identified. The left-sided plantaris muscle had two distinct heads that fused into a common tendon that was inserted into the calcaneal tuberosity. Knowledge of these variants is important, due to their close relationship with the popliteal neurovascular bundle. Clinicians should be aware, to avoid pitfalls and take them into account in their differential diagnosis.
当前的尸体报告旨在呈现小腿后群两个罕见变异的共存情况。这些变异是在对一名84岁男性捐赠尸体进行常规解剖时发现的。在左下肢，腓肠肌被确定有第三个头附着于外侧头。这种变异被称为腓肠肌第三头肌，双侧均有发现。左侧跖肌有两个不同的头，融合成一条共同的肌腱，插入跟骨结节。了解这些变异很重要，因为它们与腘部神经血管束关系密切。临床医生应予以注意，避免失误，并在鉴别诊断时将其考虑在内。
