ABSTRACT


Piriformis syndrome is an uncommon condition that causes significant pain in the posterior lower buttocks and leg due to entrapment of the sciatic nerve at the level of the piriformis muscle. In the typical anatomical presentation, the sciatic nerve exits directly ventral and inferior to the piriformis muscle and continues down the posterior leg. Several causes that have been linked to this condition include trauma, differences in leg length, hip arthroplasty, inflammation, neoplastic mass effect, and anatomic variations. A female presented with left-sided lower back and buttock pain with radiation down the posterior leg. After magnetic resonance imaging was performed, an uncommon sciatic anatomical form was identified. Although research is limited, surgical intervention shows promising results for these conditions. Accurate diagnosis and imaging modalities may help in the appropriate management of these patients.
