A Highly Unusual Source and Course of the Inferior Gluteal Nerve With Related Variations: A Case Report

Abstract

The gluteal region is rich in neurovasculature that divides in predictable ways. Though these characteristic relationships can be helpful when orienting oneself to the gluteal region, it is especially useful to be aware of anatomical variations in this region. Knowledge of such differences allows for a better appreciation of nerve entrapments and neuropathies, and such awareness is critical during surgeries. In this case report, we explore an uncharacteristic relationship among the piriformis muscle, the sciatic nerve and its components, and the inferior gluteal and posterior femoral cutaneous nerves.
