Delayed Subaponeurotic Fluid Collection in an Infant Without Trauma: A Literature Review and Case Report.

Delayed subaponeurotic fluid collections (DSFCs) are benign, focal points of fluid collection beneath the scalp's aponeurosis. We present an infant with a complicated cesarian delivery followed by a persistent, 4-cm effusion on the patient's posterior cranium that remained for 9 months. The exact etiology of this clinical manifestation remains uncertain, but some distinctive characteristics are important for early recognition to ensure proper interventions are taken if necessary.
