CRANIAL SWELLING – A DIAGNOSTIC CHALLENGE

Subaponeurotic fluid collection (SFC) is a benign cranial swelling and, probably, underdiagnosed, which arises a few weeks after birth. We describe a case of an infant with a history of a vacuum delivery and a posterior cephalohematoma reabsorbed during the neonatal period. At two months of age, develops a soft, non-tender, translucent and painless right posterior swelling without any inflammatory signs. The infant remained clinically stable, without other changes on physical examination and summary analytical study. Cranial nuclear magnetic resonance showed a subgaleal fluid collection. The diagnosis of SFC was suported and a conservative attitude was decided, with full reversal two months after. Despite the impact of their clinical presentation, it is a benign entity that health care providers should be able to identify and manage.
