Intrathoracic meningocele in association with neurofibromatosis: report of a case.

A case of intrathoracic meningocele associated with neurofibromatosis is reported. Computed tomography (CT) demonstrated that the paravertebral mass had a characteristic low attenuation coefficient compatible with liquid content. CT-myelography further confirmed the diagnosis. We recommend that though intrathoracic meningocele is rare, it should be kept in mind when making a differential diagnosis in cases where the patient has neurofibromatosis with a posterior mediastinal mass.
