Intravenous methylprednisolone-induced lower limb paraplegia exacerbation in spinal dural arteriovenous fistula: A case report / 中国脑血管病杂志

ABSTRACT

Spinal dural arteriovenous fistula (SDAVF) is difficult to make early diagnosis for non-specific clinical manifestations and imaging features. A patient of SDAVF with lower limb paraplegia exacerbation after intravenous methylprednisolone was reported. The patient was mainly characterized by low back pain and numbness of bilateral lower limbs. He was misdiagnosed as lumbar disc herniation and acute myelitis. After intravenous methylprednisolone 1 000 mg for more than 10 hours, the patient's lower limb weakness aggravated significantly than before. Later spinal angiogram confirmed SDAVF. The author summarized the clinical and imaging characteristics of SDAVF,and analyzed the diagnosis and treatment of the disease with literature review.
