Spinal meningioma in a patient with multiple sclerosis.

backgroundMultiple sclerosis (MS) is the most common immune-mediated inflammatory demyelinating disease of the central nervous system. Multiple brain and spinal tumors have been linked to MS, but a causal relationship between the two has not been determined. Here, we report a case of spinal meningioma in a patient with MS and review literature discussing the possible connection between these two disease entities. CASE DESCRIPTION: A 58-year-old female with MS presented with a 1-year history of progressively worsening back pain in conjunction with worsening right upper and lower extremity weakness. The patient was diagnosed with MS 19 months prior and had multiple known demyelinating plaques in her cervical spine. New MRI revealed an intradural extramedullary thoracic tumor with characteristics consistent with meningioma. She underwent T6- T8 laminectomies for tumor resection and pathology confirmed the radiological diagnosis. At 3-month follow- up, the patient reported complete resolution of her back pain and persistence of weakness-related gait issues.

conclusionCNS neoplasms including meningioma should be considered in MS patients presenting with newly onset neurological symptoms not entirely consistent with demyelinating disease. Both disease processes should be addressed with appropriate long-term follow-up.
