Subgaleal Collection: An Unusual Presentation of a Scalp Mass in a Pediatric Patient

Abstract

Subgaleal fluid collection is a rare phenomenon of scalp swelling among young infants and, in many cases, adolescents. As fluid accumulates in the subgaleal space, it presents as a soft, ill-defined, fluctuant, mobile swelling not limited to suture lines. This condition is associated with vacuum-assisted devices and forceps during delivery in infancy. Beyond infancy, this condition can be seen spontaneously or, most commonly, after minor head traumas. Such minor traumas that have been reported in recent years include hair pulling or hair braiding. Early recognition of this condition and its complications is essential for appropriate treatment and management. In this case report, we highlight the importance of subgaleal fluid collection being considered a differential diagnosis of headaches, particularly in children and adolescents who present with excessive hair pulling or hair braiding.
