Unilateral proptosis due to midbrain tumour. A case report.
A case of unilateral proptosis attributed to midbrain tumour is reported. The proptosis disappeared after release of intracranial hypertension. The postulated mechanism of the unilateral proptosis on the left side is a relative increase in orbital venous stasis on that side, consequent upon intracranial hypertension.
