10.3.1 Headache attributed to phaeochromocytoma.
Description:
Headache, usually bilateral and pulsating, caused by a paroxysmal rise of arterial hypertension (systolic ≥180 mm Hg and/or diastolic ≥120 mm Hg). It remits after normalization of blood pressure.
Diagnostic criteria:
- Headache fulfilling criterion C
- Both of the following:
- a hypertensive crisis1 is occurring
- no clinical features or other evidence of hypertensive encephalopathy
- Evidence of causation demonstrated by at least two of the following:
- headache has developed during the hypertensive crisis
- either or both of the following:
- a) headache has significantly worsened in parallel with increasing hypertension
- b) headache has significantly improved or resolved in parallel with improvement in or resolution of the hypertensive crisis
- headache has at least one of the following three characteristics:
- a) bilateral location
- b) pulsating quality
- c) precipitated by physical activity
- Not better accounted for by another ICHD-3 diagnosis.
Note:
A hypertensive crisis is defined as a paroxysmal rise in systolic (to ≥180 mm Hg) and/or diastolic (to ≥120 mm Hg) blood pressure.
Comment:
Paroxysmal hypertension may occur in association with failure of baroreceptor reflexes (after carotid endarterectomy or subsequent to irradiation of the neck) or in patients with enterochromaffin cell tumours.
