Nutritional ultrasound: above body mass index, two cases presentation

Malnutrition is a prevalent condition in chronic diseases, significantly impacting morbidity and mortality. Point-of-care ultrasound (POCUS) is increasingly utilized in clinical practice as a rapid and accessible tool for evaluating muscle mass. Here, we present two cases of females with chronic diseases who presented with acute exacerbations of their conditions accompanied by fluid overload. Suspected of experiencing nutritional alterations, they underwent ultrasound evaluation to confirm muscle mass loss. These cases highlight the potential of ultrasound in guiding effective muscle mass assessment, particularly in pathologies prone to fluid overload, such as chronic kidney disease and heart failure.
