Management of pediatric head trauma requires balancing accurate diagnosis and minimizing radiation exposure. Ultrasonography (US) shows potential in this area. A case study of a 10-month-old infant with acute right parietal swelling demonstrated the US’s utility in detecting a hypoechoic lesion, a suspected fracture, and a subdural hematoma. Subsequent CT confirmed the fracture, and MRI confirmed the subdural hematoma. One month later, an MRI showed hematoma reabsorption, and the US revealed an advanced bone callus. While not yet standard, the US’s ability to detect fractures in infants suggests it could indicate the need for further neuroimaging, potentially reducing ionizing radiation exposure.
