title: Spontaneous pneumocephalus following elective thoracotomy.
abstract: One month following a right upper lobectomy for bronchial carcinoma, a 50-year-old man developed headaches, confusion and a right hemiparesis. Radiographs revealed intraventricular air. This was thought to have originated from air being forced through a dural tear sustained at the time of operation. Both the intraventricular air and the accompanying symptoms and signs subsequently resolved.
