True adult lipomas have to be distinguished from angiolipomas and from epidural lipomatosis. The authors report a unique case of a patient with unilateral lumbar nerve root compression caused by extradural, intraforaminal, true adult lipoma. A 62-year-old woman suffered severe left L-5 radiculopathy that progressively worsened during the 12 months prior to presentation. She did not experience improvement with conservative therapy. An MR imaging study of the lumbar spine revealed shifting of the left L-5 nerve root caused by a small extradural intrarecessal (that is, the beginning of the intravertebral foramen)\/intraforaminal mass with MR imaging characteristics of fatty tissue. No other relevant intraspinal pathology could be identified. A left L4\u20135 fenestration was carried out. A small fatty intrarecessal\/intraforaminal mass compressing severely the left L-5 root was identified and completely resected. The histological examination revealed a lipoma. The patient recovered completely and is fully mobile and symptom free 1 year after the operation. Intraspinal lipomas should be considered in cases of radiculopathy, especially in the absence of relevant degenerative or tumorous pathology and in the presence of nerve root shifting caused by fatty tissue.<\/jats:p>","DOI":"10.3171\/spi.2008.9.11.408","type":"journal-article","created":{"date-parts":[[2008,11,3]],"date-time":"2008-11-03T15:16:22Z","timestamp":1225725382000},"page":"408-410","source":"Crossref","is-referenced-by-count":15,"title":["Lumbar nerve root compression due to extradural, intraforaminal lipoma.
