Abstract
Piriformis syndrome is a rare cause of sciatica, which results in low backache due
to sciatic nerve compression. This syndrome is associated with abnormalities in the
piriformis muscle, which cause sciatic nerve entrapment, like anatomical variations,
muscle hypertrophy, and inflammation. It can also result from the abnormal course
of sciatic nerve itself through normal piriformis muscle. Piriformis syndrome due
to pyomyositis of the piriformis muscle is extremely rare and only 23 cases are reported
in literature. Herein, we report one such rare case of a patient, with pyomyositis
of piriformis muscle, who presented with piriformis syndrome.
