We report a case of multiple anatomical variations in the right gluteal region of a 60 years old male cadaver. In the present case lower formation of the sciatic nerve was observed with the peroneal component emerging between the two parts of piriformis along with the inferior gluteal nerve and the tibial component arising inferior to it accompanied by the posterior femoral cutaneous nerve. At the lower border of piriformis, both the tibial and common peroneal components united and descended as a single trunk and further had a normal termination in the popliteal fossa. The posterior femoral cutaneous nerve (PFCN) also presented variations by forming a communicating plexus with the inferior gluteal nerve and terminated in the gluteal region. The variations in the formation of sciatic nerve, the anomalous communication and termination of the PFCN are very important for surgeons and clinicians while planning the treatment regime. Anaesthetists should also be aware of these variations during nerve blocks.
