[Transient neonatal macrocephaly. The differential diagnosis of abnormally fast-growing skull in newborn infants]. / Passagere neonatale Makrozephalie. Zur Differentialdiagnose des abnorm raschen Schädelwachstums beim Neugeborenen.

In a twin baby of low birth weight a transient abnormally increased growth velocity of the head circumference could be observed. Sodium and water retention were recognized as the underlying disturbance responsible for brain edema. This mechanism is one of several possible etiologic factors leading to macrocephaly in early infancy. Pathogenesis, therapy and prophylactic measures are discussed.
