Increased intracranial pressure in cystic fibrosis.

Three cystic fibrosis infants with severe respiratory distress had increased intracranial pressure (with bulging fontanels) which cleared parri passu with improvement in the chest condition. It is proposed that the intracranial hypertension is a result of raised venous pressure, itself secondary to the intrathoracic obstruction to venous return, consequent on the bronchial obstructive disease.
