Leiomyomas are benign tumors which are predominantly found in the genitourinary and gastrointestinal tracts. Leiomyomas in the spine are extremely rare. The current study presents a case of a 35-year-old female with intraspinal leiomyoma who presented with low back pain and weakness in the left leg of two months. Computerized tomography and magnetic resonance imaging revealed an epidural mass at the T11-12 levels. The patient underwent a T11-12 laminectomy through posterior approach, achieving total removal of the tumor with a well-demarcated dissection plane. Pathological examination demonstrated a leiomyoma. Postoperatively, the patient showed a significant improvement in neurological function. Although intraspinal leiomyoma is extremely rare, it should be considered in the differential diagnosis of spinal lesions in females. The diagnosis is predominantly dependent on a pathological examination. Gross total resection is recommended for its treatment, however the prognosis remains poor. Post-operative hormonal therapy may be useful in controlling tumor recurrence.
