Commonest site of meningocele is

• Herniation of meninges through a defect in the posterior vertebral arches. • Spinal cord is usually normal and assumes a normal position in the spinal canal • There may be tethering, syringomyelia, or diastematomyelia. Clinical Features • A fluctuant midline mass, that may transilluminate occurs along the vertebral column, in the lower back. • Most meningoceles are well covered with skin and pose no threat to the patient. • Anterior meningocele: Projects into pelvis through a defect in the sacrum. • Symptoms of constipation and bladder dysfunction develop due to the increasing size of the lesion. Diagnosis • Plain roentgenograms demonstrate a defect. Treatment • Asymptomatic children with normal neurologic findings and full-thickness skin covering the meningocele may have surgery delayed. • Patients with leaking CSF or a thin skin covering should undergo immediate surgical treatment to prevent meningitis.
