It exits the pelvis through the greater sciatic foramen…

What is piriformis syndrome and what causes it?

(Netter’s Clinical Anatomy, 2010) Piriformis syndrome occurs when the piriformis irritates the sciatic nerve, which comes into the gluteal region beneath the muscle, causing pain in the buttocks and referred pain along the sciatic nerve. This referred pain is known as sciatica.

What are the different types of piriformis anomalies?

Variation. Several variations occur, but the most common type of anomaly (81% of anomalies) is the Beaton’s type B which is when the common peroneal nerve pierces the piriformis muscle. It may be united with the gluteus medius, send fibers to the gluteus minimus, or receive fibers from the superior gemellus .
