INTRODUCTION: Split cord malformation (SCM) is an uncommon developmental anomaly characterized a cleft spinal cord. In type I, each of the hemicords is contained within an individual dural tube whereas in type II there is a common dural tube housing both hemicords. Commonly diagnosed in childhood, adult presentation is exceptional. METHODS: We report the case of two women whose type II SCM was discovered at the age of 40 and 54 years. RESULTS: The first patient complained of chronic lombar and radicular chronic pain with dysuria. Physical examination revealed a radicular syndrome with abolition of the left Achille reflex and a lombar hair tuft. MRI showed a disc herniation at the L5-S1 level, with a partial SCM at the level of the L2 vertebra, spina bifida and tethered cord. The second patient complained of lombar pain with perineal irradiation for 6 years. Physical examination showed a lombar cutaneous angioma. MRI revealed a thoraco-lombar SCM at the T12 to L1 level, with spina bifida. No spur could not be identified in either patient. No further surgical treatment was given. CONCLUSION: Based on these two observations, we propose a review of literature reporting 90 cases of adult SCM.
