title: Paraparesis after excision of intrathoracic meningoceles in a patient with neurofibromatosis.
abstract: Intrathoracic meningocele associated with neurofibromatosis is a rarity. We treated a 16-year-old boy with neurofibromatosis, marked kyphoscoliosis, and two right-sided intrathoracic meningoceles. Because his chief complaints of cough and chest pain were thought to be caused by the meningoceles, resection of these lesions was performed prior to correction of the spinal deformity. On the day after the resection, complete paraplegia developed, followed by recovery to paraparesis. Decompressive lumbar puncture was performed, but intraspinal pressure was normal. Postoperative spinal cord damage and consequent paresis may have resulted from a loss of pressure buffering by the meningocele, which rendered the cord vulnerable to injury. The possibility of a similar unusual complication should be borne in mind when treating patients with intrathoracic meningocele associated with neurofibromatosis.
