A Case of Huge Occult Meningocele on the Thoracolumbosacral Spine

ABSTRACT

Occult meningocele is a cystic type of spinal dysraphism derived from developmental fusion defect during early fetal life. It is well known its common, but remarkably less than of myelomeningocele in incidence, combinations with other anormalies. A 11-year-old boy suffering from waddling gait and equinovarus foot deformity for 6 years, is presented. He has not any external protruded mass, hypertrichosis or abnormal pigmentation around his low back. He also has no evidence of neurofibromatosis or enlarged head. Pain spinal films show widening of intervertebral foramina and interpedicular distance, and spina bifida. With myelography using 90ml of Pantopaque, huge ectatic sac accompanying with multiple outpocketings of meninges like stocked tail is well demonstrated. Neurosurgical operation was not indicated. Operation for the correction of the foot deformity were performed by orthopedician.
