Pneumocephalus after the Treatment of an Inoperable SuperiorSulcus Tumor with Chemoradiation

Pneumocephalus is a rare phenomenon that can occur as a complication after operations involving the thoracic discs,following thoracotomy for tumor resection, and after an intracranial operation or cranial trauma. %is complication frequentlyoccurs when a tumor is located in the costovertebral angle and an operative intervention creates a tear in the dura resulting ina pleural-dural .stula.Case Presentation. We describe the case of a 58-year-old man with an inoperable superior sulcus tumor whodeveloped pneumocephalus after the initiation of chemoradiation secondary to a pleural-dural .stula.Conclusions. Althougha rare occurrence, pneumocephalus should be considered when patients with tumors in the superior sulcus treated with radiationdevelop neurologic symptoms characteristic of increased intracranial pressure.
