Abstract Background This case report highlights two unusual surgical phenomena: lipoma-like well-differentiated liposarcomas and sciatic hernias.It illustrates the need to be aware that hernias may not always simply contain intra-abdominal viscera.Case presentation A 36 mintkuler year old woman presented with an expanding, yet reducible, right gluteal mass, indicative of a sciatic hernia.However, magnetic resonance imaging demonstrated a large intra- and extra-pelvic fatty mass traversing the greater sciatic foramen.The tumour was surgically removed through an abdomino-perineal approach.
