Benign Metastasizing Leiomyoma: A Case Report

Abstract

Metastasizing benign leiomyoma is an extrauterine smooth muscle tumour. Leiomyoma in spine is extremely rare. We report a case of a 47-year-old female with benign leiomyoma metastasizing to the spine. To our knowledge no case of benign leiomyoma metastasizing to the spine has been reported before. Magnetic Resonance Imaging (MRI) revealed C6, C7 vertebral involvement, T2, T4, T7, T8, T11, L2, L3, L4, L5 moderate spinal canal stenosis and cord impingement and cord compression at T12 level. She also presented with growth over her right elbow and psoas muscle. The patient underwent posterior decompression laminectomy T10-L2 instrumentation and stabilization and excision of left paravertebral mass. Histology examination of the surgical specimen shows leiomyoma. Postoperatively patient improved. Currently there is no guidelines in treating leiomyoma. Patients are treated with surgical resection, radiotherapy or hormonal treatment and radiological surveillance. Since patients present as a challenging in terms of diagnosis and management. It is important to considered as a differential diagnosis of spinal lesions in females.
