A Primary Leiomyoma in the Neural Foramen of the Lumbar Spine: A Case Report

A primary leiomyoma in the neural foramen of the lumbar spine is a very rare condition. We examined a 23-year-old female presented with back and right flank pain. A plain radiography showed a well-defined, osteolytic lesion in the L3 body. In addition, MR images showed a mass lesion with intense enhancement, after intravenous injection with contrast material, in the right neural foramen at the L2/3 level. A histopathologic examination of the resected specimen revealed a benign leiomyoma.
