title: Hypoliquorreic headache and pneumocephalus caused by thoraco-subarachnoid fistula.
abstract: One month after having a right upper lobectomy to remove a squamous cell carcinoma, a 43-year-old man presented with a 4-day history of postural headache, worsened by standing and relieved by lying. Skull films showed prominent ventricular pneumocephalus. Iophendylate myelography was unrewarding, but isotope cisternography revealed a CSF fistula at the T4 level, extending into the thoracic cavity. Thoracoplastic removal of the first four ribs successfully prevented air passage and the patient had a rapid uneventful recovery.
