title: Occult spinal dysraphism.
abstract: When spina bifida is associated with skin abnormalities such as dimples, sinus tracts hypertrichosis, or capillary hemangiomas, there is a high incidence of an occult intraspinal lesion such as epidermoid and dermoid tumours, lipomas, diastematomyelia, dural bands and tethered spinal cord. The present study consists of 50 patients with occult spinal dysraphism treated with the diagnosis of lipomeningomyelocoele (20), lumbosacral lipoma (15) and diastematomyelia (15). The clinical presentation varied from lipoma in the lumbosacral region, dermal sinus, cutaneous hemangioma and hypertrichosis. The age range varied from 2 months to 7 years with an average of 2 years. 40% patients had neurological deficit at the time of presentation which varied from lower limb weakness to bladder & bowel involvement. All patients underwent laminectomy of the lumbar and lumbo-sacral spine with excision of intraspinal lipoma, excision of bony or cartilaginous spur in diastematomyelia and detethering of the conus medullaris & cauda equina. No patient developed late neurological deficit.
