In this study, we present the ultrasound imaging features of lymph nodes arising in the regional lymph node chain after the first or second dose of the Pfizer-BioNTech COVID-19 vaccine. Ipsilateral lymphadenopathy adjacent to the vaccine injection site is an extremely rare but expected adverse reaction following COVID-19 vaccination. Although axillary lymphadenopathy is more common, cases of supraclavicular lymphadenopathy have also been reported after widespread vaccination against COVID-19. Ultrasonography examinations were performed on seven patients with no previous pathological conditions, who presented to our radiology department after receiving the Pfizer-BioNTech COVID-19 vaccine. Bilateral axillary, supraclavicular and subclavicular lymph node stations were explored. These patients typically present with enlarged hypoechoic lymph nodes with the loss of fatty hilum, asymmetric or diffuse cortical thickening, and increased hilar and cortical vascularization on the color doppler ultrasonography of the ipsilateral axillary and supraclavicular regions. Radiologists and clinicians should be aware of the ultrasonographic features of these lymph nodes and should inform the patient that these lymph nodes are often a self-limiting process. Thus, unnecessary axillary lymph node biopsies should be avoided, and patients should be treated conservatively. [ABSTRACT FROM AUTHOR]

Cervical ectopic thymus (CET) is one of the rare causes of cervical masses in childhood. These lesions manifest with the same echo and signal intensity as the natural thymus on ultrasonography (US) and magnetic resonance imaging (MRI), respectively. Therefore, both US and MRI are appropriate imaging methods for the diagnosis of CET. We evaluated the US and MRI features of the CET patient who presented to our hospital due to bilateral cervical swelling. In particular, based on the typical US appearance of thymic tissue, we believe that we can safely prevent the need for biopsy to detect that a discovered lesion that has ectopic thymus tissue. In this article, we aimed to emphasize the importance of imaging methods in the diagnosis of CET in a pediatric patient with a complaint of neck mass. [ABSTRACT FROM AUTHOR]

Aim: Comparison of the diagnostic value of ultrasonography (US) and magnetic resonance imaging (MRI) in the diagnosis of rotator cuff and biceps tendon pathologies. Material and methods: Shoulder US an MRI were performed in patients suffering from shoulder pain. The results of the two methods were retrospectively evaluated in a total of 105 cases. Magnetic resonance imaging findins were accepted as a reference. Results: In the biceps tendon, ultrasonography served as a method for correct diagnosis in 7 of the 8 cases with dislocation, in 1 of 3 cases with partial rupture, and i all 4 cases with full thickness rupture. In biceps tendon patholo- gies, the sensitivity nad the specifity of US were respectively 80% and 978%. And for supraspinatus tendon pathologies; 24 of 26 full thickness ruptures (92.3% sensitivity, 98.8% specifity), 30 of 37 partial ruptures (81% sensitivity, 95.6% specifity), 30 of 37 tendnosis' (83.3% sensitivity, 95.6% speifity) were diagnosed correctly with US. Conslusion: As a result, US is a reliable and especially reproducible method for evaluation and diagnosing of patients with shoulder pain. Furthermore, its diagnostic value is low in partial rotator cuff ruptures and in the partial ruptures of the intracapsular biceps tendon [ABSTRACT FROM AUTHOR]
