Female monozygotic twins with sacral myelomeningocele

BACKGROUND: Concurrent myelomeningocele in twins is a rare clinical presentation, only reported twice in Nigeria. CASE DESCRIPTION: We present a set of identical female twins from Nigeria. Both twins were females that presented at 3 years with low back swelling since birth, associated with bisphincteric dysfunction but normal motor and sensory functions in the lower extremities. They had repair of myelomeningocele 2 months after presentation and there was no new deficit postoperatively. There was no family history of neural tube defects and it would have been good to do genetic studies in this case but we do not have facilities for such. CONCLUSION: This is the first reported case of identical twins with concurrent myelomeningocele and preserved motor functions in the lower limbs in Nigeria and West Africa.
