title: Computed tomography of lumbar apophyseal joint lipoma: report of three cases.
abstract: The authors report three cases of lumbar apophyseal joint lipoma located at the L4/L5 or L5/S1 level. CT scan makes the diagnosis easily possible; indeed erosive changes with enlargement of the upper portion of the lumbar articular joint and anterior displacement of the top of the superior facet are associated with intra-articular fatty densities. Clinical symptoms are rarely encountered and may be related to narrowing of the upper portion of the intervertebral foramen.
