“…[ 2 ] In 1974, Tomimatsu reported the first case of an intradural-mobile schwannoma, and since then, 29 cases have been reported (Table 1 ). [ 3 – 25 ] In this case, there were 25 males and 5 females with an average age of (49.62 ± 13.88) years, and 1 case with no reported age and gender. The most common location of the lesion was in the lumbar region (60%), followed by the thoracic region (17%), the thoracolumbar junction (13%), the cervicothoracic junction (7%), and the cervical region (3%).…”

Background: Schwannoma is a benign tumor that originates from the cells of nerve sheaths. The occurrence of mobile schwannoma of the lumbar spine is extremely rare, and when clinicians perform spinal explorations in the expected locations, the results are often negative. This report presents a case of mobile schwannoma in the lumbar spine, aiming to remind doctors to consider the possibility of tumor migration during preoperative planning, thereby avoiding secondary harm to the patient. Case report: A 48-year-old male patient presented with a 2-year history of lower back pain and numbness in both lower extremities, which has progressively worsened over the past 3 months. An Magnetic resonance imaging scan revealed an oval-shaped lesion located in the L2/3 vertebral segment, which migrated to the L3/4 vertebral segment following contrast enhancement. The patient underwent tumor resection surgery, and the diagnosis of schwannoma was confirmed through pathological examination. Conclusion: Clinical physicians should increase their understanding of mobile schwannoma of the lumbar spine and utilize imaging techniques to accurately locate the tumor before surgery, in order to avoid unnecessary surgical scope and the risks of additional surgery.

BACKGROUND Intradural spinal tumors are an uncommon entity with a variety of pathologies and symptom patterns. Few cases reports in the literature have described tumor migration within the spinal canal. OBSERVATIONS A 38-year-old male presented with bilateral upper lumbar radicular symptoms of anterior thigh pain, with an enhancing tumor of the cauda equina initially located at L1–2. He declined surgery initially, and at a follow-up 3 years later, his symptoms were unchanged but the tumor was now located at T12–L1. He again declined surgery, but 3 months later, he had a significant change in his pain distribution, which was now along his posterolateral right leg to his foot with associated dorsiflexion and extensor hallicus longus weakness. At this time, the tumor had migrated to L2–3. He underwent laminectomy and tumor resection with resolution of his radicular symptoms and improvement in his strength back to baseline by the 1-month follow-up. Pathology was consistent with a World Health Organization grade I schwannoma. LESSONS Migratory schwannoma is a rare entity but should be considered when radicular symptoms acutely change in the setting of a known intradural tumor. Repeat imaging should be performed to avoid wrong-level surgery. Intraoperative imaging can also be used for tumor localization.
