Chest plain radiograph findings before and after 3 months of thoracoscopic plication. (A) A large opaque shadow was seen in the right lung field with atelectasis of the lower lobe and kyphoscoliosis of thoracic spine was marked. (B) T2-weighted magnetic resonance imaging showed cerebrospinal fluid signal intensity and a meningeal cystic lesion protruding through the right neural foramen at T4. (C) The catheter was inserted into the meningocele, and the purse-string suture was tied under thoracoscopic guidance. (D) Postoperative chest radiograph at 3 months later showed marked regression of the intrathoracic meningocele.
