Follow up data
| Total (n = 31) | Observation (n = 10) | Surgery (n = 21) | |

| *Does not include one patient who died two months after diagnosis. | |||
| †Numbers in brackets in the observation and surgery columns refer to the percentage of the total number of patients in the first column. | |||
| ‡Numbers of patients in surgery column experiencing an improvement or worsening is greater than the total number because several patients experienced improvement or worsening in more than one symptom. | |||
| §One patient experienced worsening of CIII nerve palsy and developed a new ipsilateral CVI nerve palsy and a trigeminal sensory neuropathy. | |||
| ¶One patient experienced worsening of CVI nerve palsy and developed a new headache. | |||
| CCA, cavernous sinus aneurysm; CCF, carotid–cavernous sinus fistula; HA, headache; N/A, not applicable; OMNP, oculomotor nerve palsy. | |||
