Craniocephalic disproportion with increased intracranial pressure and brain herniation: a new clinical syndrome in anemic patients: report of two cases.
OBJECTIVE
We describe a new clinical syndrome in two patients with chronic anemia. The major manifestation of the syndrome is herniation of the brain resulting in death caused by longstanding craniocephalic disproportion. The disproportion was caused by extreme thickening of the cranium because of erythroid hyperplasia.


METHODS
Two patients with known chronic anemia presented with chronic increase in intracranial pressure with acute deterioration resulting in brain herniation.


METHODS
Despite maximum medical therapy, both patients died as a result of uncontrollable increase in intracranial pressure.


CONCLUSIONS
Patients with chronic anemia presenting with progressive headaches should be monitored for this newly described clinical phenomenon.
