title: Pneumocephalus secondary to spontaneous bronchial-subarachnoid fistula.
abstract: We describe a patient in whom pneumocephalus appeared spontaneously, resulting from a communication between the bronchial tree and the thoracic subarachnoid space in association with squamous cell carcinoma of the lung. The communication was demonstrated by myelography and obliterated surgically. A review of the literature is included.
