The Use of POCUS to Identify Subgaleal Fluid Collections and Intracranial Infections
Pediatric Emergency Care
|December 10, 2024
Summary
Point-of-care ultrasound (POCUS) can identify intracranial infections like Pott's puffy tumor by showing fluid under the scalp and bone lifting. This imaging tool helps differentiate infection from trauma in children with forehead swelling.
Area of Science:
- Pediatric Radiology
- Emergency Medicine
- Infectious Diseases
Background:
- Point-of-care ultrasound (POCUS) is established for soft tissue infections.
- Limited data exists on POCUS for intracranial infections, specifically Pott's puffy tumor.
- Forehead swelling in children can indicate serious intracranial pathology.
Purpose of the Study:
- To describe POCUS findings in pediatric intracranial infections.
- To differentiate infectious intracranial conditions from soft tissue edema.
- To evaluate POCUS as a primary imaging modality for forehead swelling.
Main Methods:
- Case series of 3 pediatric patients from a tertiary care center.
- Inclusion of 2 cases with Pott's puffy tumor/intracranial infection and 1 with soft tissue edema.
- Detailed analysis of ultrasound findings, including subgaleal collections and periosteal changes.
Main Results:
- POCUS revealed subgaleal fluid collections and periosteal lifting in intracranial infection cases.
- No bony disruption or periosteal lifting was observed in the soft tissue edema case.
- Ultrasound findings correlated with the underlying diagnosis.
Conclusions:
- POCUS can detect subgaleal fluid collections and periosteal lifting in pediatric intracranial infections.
- POCUS may serve as a valuable first-line imaging tool for forehead swelling in children.
- This technique aids in differentiating infectious from traumatic causes and guides further imaging needs.

01:25Pleural Effusion I: Introduction
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
