title: Retroperitoneal liposarcoma simulating a prolapsed intervertebral disc. A case report.
abstract: A metastatic liposarcoma presented with the clinical features of a prolapsed intervertebral disc. The tumour had spread from the retroperitoneal space in front of the sacrum by way of the first sacral foramen and along the dural sleeve of the first sacral root. Such a presentation has not previously been reported, and we make the point that it is important always to send material removed during operation on discs for histological examination.
