Increased intracranial pressure is naturally suspected in infantswith exceptionally rapid head growth, a bulging fontanelle, or separated sutures, with or without papilledema. When adequate nutrition is restored to malnourished children, one or more signs of "pseudotumor cerebri" may be observed.
Recently we saw a patient who developed a bulging fontanelle and rapid head growth ten days after initiation of treatment for cystic fibrosis. Diagnostic tests for the usually suspected diseases were promptly performed before the findings were attributed to new brain growth.
