title: Pneumocephalus secondary to lumbar catheterization.
abstract: A 60-year-old woman with a history of chronic back pain presented to the emergency department with headache, slurred speech, and altered sensorium reported by her family. The previous day, she had a lumbar catheter placed for symptomatic relief of her chronic back pain. The patient complained only of headache, but otherwise thought she was unaffected. The patient's past medi- cal history was remarkable for diabetes, hypertension, peripheral neuropathy, gastritis, supraventricular tachycardia, and chronic back pain. On physical examination she was alert, fully orientated, and in no acute distress. Her vital signs were normal. Neurological examination revealed subtle word-finding difficulties and dysarthria. There were no physical signs of raised intracranial pressure (ICP). The remainder of her examination was entirely normal.
