Diastematomyelia- An Unusual Presentation to Rheumatology
Diastematomyelia is classified as a rare congenital anomaly (1) and is one of two types of 'split cord' malformations (2) which can occur as part of a spectrum of neural tube defects. As in our case, it is often associated with Spina Bifida and is more common in females. It accounts for approximately 5% of all congenital spinal defects (3) and is manifested as a longitudinal split in the spinal canal. The most common location of the lesion is L1-L3, also in keeping with this case presentation.
