Serial spread of benign metastasizing leiomyoma to the thoracic spine

Abstract Benign metastasizing leiomyoma (BML) is a rare condition due to a histologically benign smooth muscle tumour originating from a uterine leiomyoma. It rarely affects the spine to cause spinal cord compression. Here we report a patient with serial metastases to the thoracic spine causing neurological compromise. The rapid spread of BML in this patient illustrates an aggressive manifestation of a usually benign indolent tumour.
