A repeat CT showed near-complete resolution of her pneumocephalus [Figure 2], but her persistent symptoms prompted us to use magnetic resonance imaging (MRI) of her cervical, thoracic, and lumbar spine to assess whether she had a cerebrospinal fluid leak [Figure 3].
Sagittal MRI of cervical, thoracic, and lumbar spine obtained to evaluate the patient for a possible cerebrospinal fluid leak. No obvious source of leakage was identified
