Ultrasound characteristics of extravaginal testicular torsion at different stages of disease progression.

Background: Extravaginal testicular torsion has profound clinical implications in neonates, but its ultrasound characteristics may vary at different disease stages. The purpose of this study was to identify the ultrasound characteristics of neonatal extravaginal testicular torsion and their diagnostic value at different disease stages.

Methods: A retrospective analysis of the clinical and ultrasound examination data of 20 infants aged 1-75 days with surgically and pathologically confirmed unilateral extravaginal testicular torsion (10 right, 10 left) was conducted.

Ultrasound diagnosis of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion in children and adolescents.

Background: Many studies have reported Xp 11.2 translocation renal cancer in radioimaging,but there is little literature on the evaluation of Xp11.2 translocation renal cell carcinoma by ultrasound.

Failure to achieve reduction on developmental dysplasia of hip: an ultrasound evaluation.

Background: Ultrasound examination of the medial side of the hip joint has been rarely used to evaluate the status of developmental dysplasia of the hip (DDH) in Pavlik harness treatment according to the literature.

Purpose: To analyze the effects of cartilaginous acetabulum, hip joint labrum, and acetabular tissue on the reduction of DDH.

Material And Methods: A total of 50 cases (100 hips) were detected by the Graf method with a high-frequency linear transducer (L 5-12), and there were 59 dislocated hips and 41 non-dislocated hips.

Use of ultrasonography to evaluate early outcomes of reduction in developmental dysplasia of the hip.

Objective: To compare pubo-femoral distance (PFD) in normal hips and those treated for developmental dysplasia of the hip (DDH) and to investigate the value of ultrasonography from the medial hip in early follow-up of dislocated DDH after reduction.

Materials And Methods: This study included 58 infants (49 females) with DDH who presented with 65 dislocated hips (51 unilateral and 7 bilateral). Dislocation was treated by closed reduction for 53 and open reduction for 12 hips.

Establishing reference values for the pubofemoral distance in normal infant medial hips by ultrasound.

Background: Measuring the pubofemoral distance (PFD) is important for evaluating the effectiveness of hip reduction in the treatment of developmental dysplasia of the hip (DDH). However, reference PFD values have not been established in normal infants.

Purpose: To investigate variations in PFD values measured in normal infant medial hips stratified by age, laterality, and gender.

The relationship between density variations of transverse ligament tubercles on multidetector computed tomography (MDCT) and age, gender, or laterality in a large cohort.

Background: Transverse ligament tubercles are unique structures that maintain the stability of the upper cervical spine. However, the density variations of tubercles in different clinical contexts or populations have not been carefully studied through multidetector computed tomography (MDCT).

Purpose: This study aimed to evaluate the relationship between density variations in the transverse ligament tubercles, as measured through multidetector computed tomography (MDCT), with age, gender, or laterality.

Variation of bilateral transverse ligament tubercles with age and gender in a large series of subjects on multidetector computed tomography.

Background: The transverse ligament tubercles play an important role in maintaining the stability of upper cervical spine, but the variation of these tubercles with aging has not been studied systematically.

Purpose: To evaluate the variation of the height of the transverse ligament tubercles with respect to age and gender, and assess side-to-side differences on multidetector computed tomography (MDCT).

Material And Methods: A consecutive series of 291 Chinese patients undergoing a head or neck MDCT were divided into eight age groups.

Sonographic appearances of desmoid tumors.

The medical records of 16 patients (9 female and 7 male; age range, 5-66 years) with 24 lesions that had a histologic diagnosis of desmoid tumors were reviewed at our institution. Six cases were extra-abdominal, 4 intra-abdominal, and 6 in the abdominal wall. Lesions ranged from 1.
