“…Earlier studies have suggest that peritumoral hyperechogenicity is caused by the surrounding edematous stroma,[ 16 17 ] and is associated with inflammation. [ 22 23 24 25 26 ] Some patients in the present study had a relatively longer symptom duration but exhibited peritumoral hyperechogenicity on sonography. Pilomatricomas are sometimes accompanied by chronic inflammation with foreign body reaction and proliferation of multinucleated giant cells and lymphocytes.…”

This study aimed to investigate the associations between the sonographic findings and duration of symptoms in children with pilomatricoma. This study included 86 children with 95 lesions confirmed to be pilomatricoma after pathological examination. The associations between symptom duration and sonographic observations, including the presence or absence of peritumoral hyperechogenicity, calcification, and vascularity were investigated. The internal echogenicity of each pilomatricoma was scored using a 5-point scale based on echogenic spots and calcification with posterior acoustic shadowing. The Mann–Whitney U and Kruskal–Wallis tests were used for statistical analysis. We found that the absence of peritumoral hyperechogenicity and severity of calcification were associated with increased symptom duration. Calcification, (present, 19.19 ± 18.99 months vs absent, 4.31 ± 3.24 months; P < .01) and peritumoral hyperechogenicity (present, 5.02 ± 5.80 months vs absent, 16.17 ± 18.24 months; P < .01), and grade of internal echogenicity (grade 0/1/2/3/4 = 3 months [1 patient]/4.33 ± 3.26 months [range, 1–12]/4.57 ± 3.46 months [range, 2–12]/10.89 ± 9.17 months [range, 3–28]/35.27 ± 19.16 months [range, 9–60], respectively; P = .01 and <.01) were associated with significant differences in symptom duration. There were no significant between-group differences in vascularity (6.01 ± 7.24 months; range, 1–48 vs 15.50 ± 19.12 months; range, 1–60; P = .08). Pilomatricomas with a relatively short symptom duration were more likely to exhibit peritumoral hyperechogenicity and calcification with less severe posterior acoustic shadowing compared to lesions with a longer symptom duration. These sonographic findings provided useful information that facilitated the correct and rapid diagnosis of pilomatricoma.

“…Therefore, the thymus is usually visualized via the parasternal or suprasternal notch approach using a linear transducer (9-15 MHz) or convex transducer (2-9 MHz). The suprasternal notch is recessed; therefore, a convex probe may be useful to evaluate the anterior mediastinum [13] , [14] , [15] , [16] , [17] , [18] , [19] . T-ALL is a neoplasm of immature T-lineage cells [1] .…”

“…In ultrasound to evaluate the SSI, classification based on the extent of inflammation is important. In cases of SSI after cardiovascular surgery, SII or DII were detected with a higher occurrence of increased parasternal fat echogenicity, and organ/space SSI was detected as retrosternal mediastinal fluid collection [ 97 , 98 ]. None of the patients without mediastinal fluid collection or increased fat echogenicity was diagnosed with organ/space SSIs [ 98 ].…”

Background Infectious diseases are common in pediatric patients. In these patients, ultrasound is a useful imaging modality that involves no irradiation or sedation and can be performed repeatedly at the patient’s bedside. The purpose of this review was to show pediatric cases with infectious disease that used ultrasound to decide the methods of treatment. Data sources Literature review was performed using Pubmed as the medical database source. No year-of-publication restriction was placed. The mesh terms used were: “ultrasound”, “sonography”, “infectious disease”, “treatment”, “antibiotics”, “surgical intervention”, “pediatric”, “children”, “deep neck abscess”, “pyothorax”, “empyema”, “pneumonia”, “urinary tract infection”, “intra-abdominal abscess”, “soft tissue infection”, “septic arthritis”, “osteomyelitis”, and “surgical site infection”. Results We presented pediatric case series with infectious diseases, including deep neck abscess, pyothorax and empyema, pneumonia, urinary tract infection, intra-abdominal abscess, soft tissue infection, septic arthritis and osteomyelitis, and surgical-site infection. Ultrasound was useful for evaluating the extent and location of inflammation and abscess and for decision-making concerning surgical intervention. Conclusion Knowledge of these sonographic findings is important for sonographers during examinations and for physicians when determining the treatment plan and period of antibiotic therapy for infected lesions.
