Meralgia paresthetica is a sensory mononeuropathy of the lateral femoral cutaneous nerve that remains frequently underdiagnosed despite its characteristic clinical presentation. Burning pain, paresthesia, and numbness over the anterolateral thigh may mimic hip, lumbar, or pelvic disorders, contributing to diagnostic delay. Imaging has gained increasing relevance in the evaluation of meralgia paresthetica, both for confirming neuropathy and for identifying contributory anatomical factors. High-resolution ultrasound enables direct visualization of the lateral femoral cutaneous nerve, characterization of its anatomical variants, and detection of focal changes at typical entrapment sites.

Ultrasound-guided interventions in the ankle and foot are safe, accurate, and effective procedures for both diagnostic and therapeutic management of soft-tissue and joint diseases. They are increasingly popular due to advances in ultrasound technology and the increasing availability of ultrasound scanners. These procedures can be performed in an outpatient setting using high-resolution scanners with high-frequency linear probes under sterile conditions, using sterile equipment, supported by standardized pre- and post-treatment protocols.

The common peroneal nerve is one of the most frequent sites of neuropathy around the knee. Owing to its superficial course, it is highly vulnerable to both trauma and mechanical compression. High-frequency ultrasonography enables real-time, dynamic evaluation of the common peroneal nerve along its entire trajectory from the popliteal fossa to the exit from the peroneal tunnel. This article presents a stepwise, structured ultrasound protocol for the assessment of the common peroneal nerve in the peri-knee region. Supported by illustrative images and videos, the protocol is expected to facilitate practical applicability in daily practice and improve diagnostic accuracy.

Meniscal injuries are frequent findings in clinical practice and may arise from acute trauma, progressive degeneration, or joint instability. While MRI remains the gold-standard modality for identifying these lesions, ultrasound has emerged as a valuable complementary technique thanks to its accessibility, low cost, real-time capability, and ability to perform dynamic assessments at the point of care. Increasingly, clinicians and radiologists are relying on ultrasound to detect and characterize subtle meniscal abnormalities that might otherwise be missed or underestimated.

High-resolution imaging has transformed the evaluation of small superficial peripheral nerves, enabling earlier detection of neuropathies, traumatic injuries, and entrapments. Among available modalities, ultrasound is particularly well suited for this purpose owing to its high spatial resolution, dynamic assessment capabilities, and ability to guide interventions.

To review the anatomy, biomechanics, ultrasound technique, and imaging features of the distal tibiofibular syndesmosis, and to highlight the role of ultrasound relative to MRI in evaluating syndesmotic injuries. A literature-based narrative review was performed, focusing on normal and pathologic ultrasound findings of the syndesmotic ligaments and their MRI correlation.

The aponeurotic expansion of the supraspinatus tendon is a recognized but underappreciated anatomical structure of the shoulder. Its sonographic appearance may mimic or coexist with pathology of adjacent tendons, particularly the long head of the biceps tendon, creating diagnostic challenges. Although described in prior literature, many atypical variants remain insufficiently documented. This study aimed to characterize atypical sonographic manifestations of the aponeurotic expansion of the supraspinatus tendon and to propose new classifications based on its relationship with the supraspinatus tendon, its position within the rotator interval, and its association with the long head of the biceps tendon.
