Sciatic nerve is the thickest and largest nerve of the body arising from the sacral plexus. It begins in the pelvis and divides at the superior angle of popliteal fossa into tibial and common peroneal nerve. Here, we report an anomalous high division of sciatic nerve in the pelvis in a male cadaver during routine anatomical dissection. This condition is referred to as eventration of sciatic nerve, the knowledge of which is important during surgeries in the gluteal region. Variations of nerve are not only of anatomical and embryological interest but also of clinical importance, as these can be the etiological factors in various pathological conditions like piriformis syndrome, sciatica and coccygodynia. This type of variation may lead to failed sciatic nerve block during pain management of sciatica and other lower limb surgeries.
