RESUMO
Contrast-enhanced ultrasound scan (CEUS) is the application of ultrasound contrast agents (UCAs) to traditional ultrasound. Our aim is to report the use of CEUS for a prompt assessment of a suspected secondary splenic lymphoma in a child, which, in our experience, has allowed an accurate description of the parenchymal perfusion and vascularization pattern, leading to a confident diagnosis. We suggest that CEUS will replace Magnetic resonance imaging (MRI) or Computed tomography (CT) as standard imaging option for differential diagnosis of spleen lesions in pediatric population. As a result this will lead to decreasing the overall use of ionizing radiation and reducing the time interval to a certain diagnosis.
RESUMO
Neonatal breast enlargement is a hormone-related condition, mostly asymptomatic\physiological, with a well-recognizable sonographic appearance but limited data in the literature. It can be uni-or bilateral. Typically described in the first week of life, the transient lesion disappears spontaneously within 6 months. The main differential diagnosis is neonatal mastitis, a breast tissue infection that requires a specific antibiotic therapy. Knowledge of clinical and imaging findings is crucial, and ultrasound represents a reliable tool which allows a quick identification and an excellent examination of neonatal breast abnormalities. We aim to highlight sonographic classic features of benign neonatal breast enlargement showing how ultrasound rules out real breast masses helping to differentiate between it and mastitis when clinical and laboratory data are inconclusive. We describe a 2-day-old male with bilateral breast swelling more pronounced on the right side.
