AbstractPoint-of-care ultrasound (POCUS) has been useful in describing soft tissue infections, such as cellulitis and abscesses. There has been limited use of ultrasound to describe findings of intracranial infections, such as Pott's puffy tumor, in cases of forehead prominence and signs of infection. In this case series we present POCUS findings in 2 cases of intracranial infections and one case of soft tissue edema without intracranial involvement from a single pediatric tertiary care center. Ultrasound findings revealed subgaleal fluid collections with associated periosteal lifting of the frontal bone in cases of Pott's Puffy tumor and intracranial infection, but no bony disruption or periosteal lifting in the patient with traumatic soft tissue edema. As pediatric intracranial infections may continue to have uncharacteristic seasonal peaks, POCUS may be considered as a first-line imaging technique for patients presenting with forehead swelling for differentiating infectious and traumatic etiologies as well as judging the need for further imaging techniques such as computed tomography and magnetic resonance imaging.Copyright © 2024 Wolters Kluwer Health, Inc.
