Ligamentum flavum hematoma in the thoracic spine

We report a case of a hematoma of ligamentum flavum at T11-12 in a 66-year- old man who presented with progressive weakness of the right foot and numbn ess of both legs. Past history was negative and no precipitating episode of lower back sprain or trauma. The resected T11 and T12 laminas showed old h ematoma with degenerative changes in the ligamentum flavum. Hematoma occurr ing in the thoracic spine has never been reported previously. (C) 2001 Else vier Science Inc. All rights reserved.
