Case Report Extraskeletal Chondroma: Another Diagnostic Possibility for a Soft Tissue Axillary Mass in an Adolescent

Extraskeletal chondroma is a benign cartilaginous tumor that occurs predominantly in the soft tissues near small joints of the hands and feet. There are rare reports of the lesion in other sites, such as the head, neck, trunk, oral cavity, larynx, and pharynx. We present a case of an axillary mass in a 15-year-old girl who underwent MRI examination and resection, with the ultimate diagnosis of an extraskeletal chondroma, in order to expand the differential diagnosis of an axillary soft tissue mass in an adolescent

Intraabdominal extrapulmonary sequestration diagnosed by color doppler ultrasound at 22 weeks' gestation

Intraabdominal extrapulmonary sequestration is seen very rarely. When a left suprarenal mass is detected in prenatal sonography, vascularization of the lesion should be evaluated with color Doppler sonography. We present a case of intraabdominal extrapulmonary sequestration that was diagnosed by color Doppler ultrasound at 22 weeks' gestation. (c) 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 201

Generalised lymphangiomatosis in an 8-year-old girl who presented with cardiomegaly

Generalised lymphangiomatosis is a rare disease that is characterized by widespread bony and soft tissue involvement of lymphangioma. Radiological evaluation is crucial because the site and extent of the lymphangioma are important prognostic factors. The computed tomography, ultrasonography and magnetic resonance images showed sharply defined, non-enhanced cystic lesions involving the mediastinum, bones, spleen, lung, and lower neck. We report here a case that was referred to us for investigation of marked cardiomegaly

Evaluation of Periarticular Soft Tissues in Patients With Juvenile Idiopathic Arthritis by Superb Microvascular Imaging and Shear Wave Elastography

Objectives: This study aims to compare the vascularity and elasticity of periarticular soft tissues by superb microvascular imaging (SMI) and power Doppler (PD) ultrasound along with shear wave elastography (SWE) between children with juvenile idiopathic arthritis (JIA) and healthy children

Quantitative Assessment of Palatine Tonsils in Healthy Children and Adolescents With Shear-Wave Elastography

The normal elasticity and velocity values for palatine tonsils (PTs) in healthy children and adolescents were defined using shear wave elastography, and the relationship with potential factors affecting these values was assessed. This prospective study included a total of 80 cases with ages ranging from 3 to 17 years. Sex, age, and body mass index (BMI) were recorded. Elasticity and velocity measurements of both PTs and the relationship with basic descriptive data were investigated. For statistical analyses, independent-samples t tests and Spearman rho (r) correlation coefficient were used. Quantitative variables are shown as the mean +/- SD, and categorical variables are shown as n (%). The mean age was 10.6 +/- 6.4 years, and the mean BMI was 17.40 +/- 4 kg/m(2). The mean elasticity and velocity values were 9.38 +/- 1.27 kPa and 1.76 +/- 0.11 m/s for the right PT and 9.57 +/- 1.43 kPa and 1.79 +/- 1.04 m/s for the left PT, respectively. The mean tonsil volume was 2.44 mL for the right PT and 2.36 mL for the left PT. There were no significant differences in elasticity, velocity, and volumes when comparing location, age, or sex groups. No significant correlations were observed between the elasticity and velocity values and BMI. In conclusion, this preliminary work can be used as a reference for the diagnosis of PT diseases. Future comprehensive studies are necessary to establish the role of elastography in the diagnosis of pathologic tissue differentiation confirmed by clinical, laboratory, or pathology analyses

Enteroclysis in older children and teenagers

Background Enteroclysis (EC) has been widely and successfully used for evaluation of the small bowel in adults for about 30 years. However, despite recently improved intubation and examination techniques, in many paediatric radiology centres it is still not the preferred conventional barium study for the evaluation of small bowel pathology in children

Normative values of pancreas stiffness by shear wave elastography in healthy children and adolescents

Purpose To define normal pancreas elasticity and velocity values with shear wave elastography (SWE) in healthy children and assess associations with gender, age, and body mass index (BMI). Methods This prospective study included a total of 100 cases (male: 50; female: 50), aged 3-17 years. Preschool, school, and adolescent periods of 3-6 years (n = 27), 7-12 years (n = 30), and 13-17 years (n = 43), respectively, were created in addition to two groups representing prepubertal and postpubertal periods of 3-10 years (n = 50) and 11-18 years (n = 50), respectively. Demographic data regarding the gender, age, height, body weight, and BMI were recorded. Pancreatic head, corpus, and tail SWE measurements were performed with a convex transducer (3.5-5 MHz). Correlations and comparisons were made for stiffness values between groups. Statistical analyses used Mann-WhitneyU, Kruskal-Wallis, and Spearman's correlation tests. Results Medians (25-75th percentage) of age and BMI were 7 (4.25-10) years and 15 (13-17) years and 17.47 (14.94-19.23) kg/m(2)and 21.22 (17.41-24) kg/m(2)in the two age groups, respectively. The median (interquartile range) elasticity and velocity values for the head, corpus, and tail sections of the pancreas were measured as 9.35 (2.9) kPa and 1.76 (0.26) m/s; 9.3 (2.5) kPa and 1.74 (0.21) m/s; and 8.75 (2) kPa and 1.69 (0.15) m/s, respectively. No significant differences were identified for stiffness values between gender and pancreatic section. Pancreatic stiffness values were significantly different among two (p = 0.001) and three (p = 0.028) age groups, and presented mild positive correlations with age (r: 0.23,p: 0.002), height (r: 0.18,p: 0.01), body weight (r: 0.38,p: 0.003), and BMI (r: 0.37,p: 0.045). Conclusion Normal elasticity and velocity values were defined for the pancreas with SWE in children. Pancreatic stiffness does not significantly change among pancreas parts, but it increases with the transition from childhood to adolescence
