A case report of sciatic hernia as a cause of sciatica and lower back pain: Diagnostic dilemma for family physicians.

ABSTRACT

Degenerative changes in lumbosacral spine or disc bulges impinging on the thecal sac are the usual causes of sciatica. However peripheral compression of sciatic nerve in pelvis or lower limb presenting as sciatica is an uncommon entity. The sciatic hernia is a rare type of hernia. Due to the deep location of this pathology, the clinical examination would add little and imaging plays a pivotal role in diagnosis. We present a case of sciatica diagnosed with giant gluteal lipoma presenting as sciatic notch hernia and compressing sciatic nerve in the greater sciatic notch. Less than 100 cases are reported in the literature so far. The possibility of this rare diagnosis should be kept in mind by family physicians while evaluating patients of sciatica with no significant imaging findings in lumbosacral spine.
