“…The axial scans are done first because they provide more panoramic views. Areas of interest are then explored with longitudinal scans [9]. A fundamental landmark in examinations of the cranial portion of the RF is the anterior superior iliac spine, which can be readily identified by palpation.…”

“…Axial scans of the RF muscle reveal its characteristic internal architecture, which is related to the presence of the vertical aponeurosis [9]. The latter is represented by a mildly curved, comma-shaped hyperechoic structure, which is normally quite distinct from the muscle tissue and extends as far as the lower third of the muscle [9,15].…”

Lesions of the quadriceps muscle (QM) are frequently seen by sonographers, and in most cases they are the result of sports-related trauma. An accurate assessment of the severity of the lesion is essential, particularly when the patient is a professional athlete. In most cases, careful history-taking and a thorough physical examination are sufficient for making the diagnosis and indicating the most suitable imaging studies for each case. Clinical assessment alone, however, may not be sufficient for distinguishing contusions from small, partial tears or for estimating the size of a tear. Therefore, at least in patients who are professional athletes, imaging studies are necessary to plan appropriate therapy that will allow prompt functional recovery.Muscles cannot be visualized with conventional radiography, but it is used routinely in prepubertal patients because it can detect apophyseal detachments, which are the most frequent muscle lesion in this age group. Radiography is also useful when myositis ossificans is suspected. Magnetic resonance imaging, thanks to its excellent tissue contrast, allows simultaneous assessment of muscle, joint, and bone planes. It remains a second-line study due to its high cost and relatively low availability. It is also associated with various contraindications, the most important of which is the presence of a cardiac pacemaker. Ultrasonography has a number of advantages, including widespread availability, absence of contraindications, and low cost. It can also be used for dynamic studies of the muscle during contraction and relaxation, and if doubts arise, scans can easily be obtained of the contralateral muscle for comparison purposes. These qualities make it an excellent tool for follow-up of patients with QM lesions, when follow-up is necessary. This article reviews the anatomy of the QM, the technique used for standard ultrasound examination of this muscle, its normal appearance on ultrasound, and the sonographic characteristics of the most common traumatic lesions that affect it.Sommario Le lesioni del muscolo quadricipite (MQ) sono frequenti nella pratica ecografica quotidiana e, nella gran maggioranza dei casi, sono secondarie a traumi, per lo più sportivi. Un'accurata valutazione della gravità delle lesioni è necessaria, in particolare quando siano coinvolti sportivi di alto livello. * Corresponding author. CIM SA, Route de Malagnou 40a,
