Pneumocephalus is a common occurrence after cranial surgery, with patients typically remaining asymptomatic from a moderate amount of intracranial air. Postsurgical pneumocephalus rarely causes focal neurological deficits; furthermore, cranial neuropathy from postsurgical pneumocephalus is exceedingly uncommon. Only 3 cases have been previously reported that describe direct cranial nerve compression from intracranial air resulting in an isolated single cranial nerve deficit. The authors present a patient who developed dysconjugate eye movements from bilateral oculomotor nerve palsy. Direct cranial nerve compression occurred as a result of postoperative pneumocephalus in the interpeduncular cistern. The isolated cranial neuropathy gradually recovered as the intracranial air was reabsorbed.
