Emesis-induced sub-periosteal haematoma: a case report.

BACKGROUND

Orbital sub-periosteal haematoma (OSH) is usually caused by orbital trauma. We present a case of spontaneous OSH and review the literature on this condition.

METHODS

We present a case of sub-periosteal haematoma secondary to migraine and vigorous emesis.

DISCUSSION

OSH is very rare; this case highlights the clinical features of the condition and that rapid spontaneous resolution can occur. We review the literature on emesis- or valsava-induced OSH and discuss possible mechanisms for its formation in conjunction with migraine.
