Background To our knowledge, no systematic study has been conducted on computed tomography (CT) imaging of mediastinitis in children post‐cardiovascular surgery. We aimed to assess the CT findings of pediatric patients diagnosed with mediastinitis after cardiovascular surgery. Methods We included 28 pediatric patients with suspected mediastinitis after undergoing cardiovascular surgery and who underwent CT. Patients were divided into a group with mediastinitis requiring antibiotic therapy (n = 15) confirmed by positive bacterial culture from the mediastinum and a group without mediastinitis (n = 13). Fisher's exact test was used to compare the following CT findings between the two groups: (i) mediastinal fluid collection; (ii) free gas bubble within fluid collection; (iii) sternal destruction; and (iv) capsular ring enhancement. The enhancement extent was categorized into the following four grades: whole rim enhancement, >50% of the rim enhancement, <50% of the rim enhancement, and no rim enhancement. A receiver operating characteristic curve analysis was performed to establish a cut‐off point for obtaining the maximum diagnostic accuracy. Results A significant difference was observed between patients, with and without mediastinitis in sternal destruction (73.6% vs 0%, P = <0.0001) and capsular ring enhancement (100.0% vs 38.5%, P = 0.0004). By using a cut‐off grade of the whole rim enhancement, the estimated sensitivity and specificity for mediastinitis diagnosis were 100% and 92.3%, respectively. Conclusion Computed tomography findings of sternal destruction and capsular ring enhancement were observed more in patients with mediastinitis than in those without mediastinitis, and should be assessed carefully to diagnose mediastinitis accurately in pediatric patients who have undergone cardiac surgery.

“…These findings are necessary for a diagnosis of mediastinitis to be made, and this result is consistent with previous report. 19,28 Moreover, the patients in this study with hematomas had various grades of capsular ring extent. There were some studies reporting that chronic hematoma may cause various enhancements.…”

“…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] .…”
