Occult spinal dysraphism. Case report and review of the literature

This case report and review of the literature is presented to create a greater diagnostic awareness of occult spinal dysraphism. Early recognition is based upon an understanding of this congenital anomaly and its variable presentations. These most commonly include abnormal gait, various cutaneous manifestations, particularly subcutaneous lipomata, and less frequently urological complaints. Surgical intervention, to arrest disease progression, is the primary mode of treatment, and functional improvement is variable. Long-term prognosis is dependent upon severity of neurologic deficits prior to surgery and the type of lesion found intraoperatively. Familial occurrence has been reported and genetic counseling may be an important preventive measure. Recent radiologic investigations have been concerned with the use of ultrasonography in screening infants at risk.
