Abstract：Objective To study the clinicopathological features,diagnosis and differential diagnosis of intraspinal nerve sheath myxoma.Methods We described a case of intradural extramedullary spinal nerve sheath myxoma and reviewed the related literature.Results A 53-year-old male patient presented with bilateral lower limbs weakness and MRI revealed a well-demarcated intradural extramedullary tumor at the L1 lever.Histological study revealed characteristic myxoid lobules that were separated by fibrous septa or bands of more compact cellular area.The tumor ceils were diffusely positive for S-100 at cytoplasm and nucleus.Conclusion Intraspinal nerve sheath myxoma is extremely rare.Diagnosis is confirmed by combining pathology with immunohistochemistry.Literatures revealed most intraspinal nerve sheath myxomas are located at lower segment of spinal cord.There is a slight predominance in males.No recurrences are reported.
