A paralabral cyst of the hip joint causing sciatica: case report and review of literature.

The prolapse of the intervertebral disc is most common cause of sciatica; rare causes of sciatica are pelvic fractures, pelvic tumors, piriformis syndrome, a rupture of medial head of gastronemius and sacroiliac joint dysfunction. We report the case of a 30-year-old male with a paralabral cyst of the hip joint with an acetabular labral tear causing sciatica. Our patient had an acetabular labral tear caused by a repetitive micro-trauma and external rotation injury. The diagnosis of the paralabral cyst with acetabular labral tear was based on clinical examination and histopathological examinations, and Magnetic resonance imaging findings. The patient underwent successful surgical excision of paralabral cyst and surgical repair of an acetabular labral tear. The present case reinforces the need for clinicians to be vigilant about rare causes of sciatica.
